The development processing apparatus according to the present invention will be described below. In the developing apparatus for a photosensitive material according to the present invention, V / L ≦ 25 when the tank capacity of the developing section is V milliliter and the path length from the inlet to the outlet of the photosensitive material is L centimeter. A characteristic feature is that a processing tank satisfying a certain condition is used, and a preferable mode for achieving this condition is, for example, a processing tank (processing) in which a processing liquid for processing a photosensitive material is stored and formed in a V shape. Tank), a guide part which is formed by a part of the inner wall surface of the processing tank and guides the photosensitive material and constitutes a transfer path of the photosensitive material, and the photosensitive material which is arranged in the processing tank and transfers the photosensitive material along the transfer path. A photosensitive material processing apparatus having a transporting means and a photosensitive material processing apparatus in which a processing tank forms a slit-shaped processing path. Here, the path length refers to the length from the point where the silver halide photographic light-sensitive material comes into contact with the processing solution in the processing tank to the point where it is carried out from the processing solution, and here, the tank capacity ( V) excludes the amount of liquid in the circulation system and the capacity of sub-tanks that may be used for temperature control of the developer. Between the tank capacity (V) milliliter and the path length (L) centimeter, V / L
It is necessary to satisfy the relationship of ≦ 25, preferably 1 ≦ V
/ L ≦ 20. Tank capacity (V) is 50-500
It is preferably in the range of 0 ml, and more preferably 100 to 3000 ml from the viewpoint of the effect. The path length (L) is generally 2 to 20, though it varies depending on the type of processing liquid and the time required for processing.
It is preferably 0 cm, and more preferably 4 to 120 cm.

FIG. 1 is a sectional view of an embodiment of a suitable photosensitive material developing and processing apparatus that can be used in the present invention. As shown in FIG. 1, the photosensitive material processing apparatus 110 according to the present embodiment is provided with a slit-shaped processing path 112 in order to reduce the processing liquid amount and perform processing easily. The slit-shaped processing path 112 used here is a cross section obtained by cutting a path in a processing tank through which a photosensitive material passes at a right angle to the traveling direction of the photosensitive material, and the cross-sectional thickness (width direction of the photosensitive material) of thickness. Means a so-called slit type. The slit shape may be rectangular or oval. Here, in this processing tank, when the thickness of the tank cross section orthogonal to the traveling direction of the photosensitive material is W, it is preferable that the condition of 0.1 ≦ W ≦ 10 cm is satisfied, and more preferably, 0. 5 ≦ W ≦ 3 cm. If W is too large, the tank capacity increases, and if it is too small, scratches are likely to occur on the photosensitive material to be processed. Further, in the processing tank, when the curvature formed by the processing path at the bottom of the processing tank is R, 10 ≦ R ≦ 70 mmφ is preferable, and further 20 ≦ R ≦ 50 mmφ is preferable. If R is too large, the processing apparatus becomes large, and if it is too small, conveyance failure easily occurs at the turn portion.

The path length of the processing path 112 is determined according to the type of processing liquid and the time required for the processing (immersion time in the processing liquid). The slit-shaped processing path 112 may be provided in all the processing tanks of the photosensitive material processing apparatus, or may be provided in a part of the processing tanks and the other processing tanks may be the same processing tanks as the conventional ones. In this photosensitive material processing apparatus 110, all processing tanks are provided with slit-shaped processing paths 112, and a developing tank 114 and a bleaching tank 11 having a path length according to the processing time are provided.
6 are arranged adjacent to each other, and the photosensitive material developed in the developing tank 114 is sent out to the bleaching tank 116 which is the next processing tank by the pair of conveying rollers 118. Further, adjacent to the bleaching tank 116, two fixing tanks 120 and a washing tank 12 are provided.
It has a structure in which one and two stabilizing tanks 122 are respectively arranged. Then, the developing solution is stored in the developing tank 114, the bleaching solution is stored in the bleaching tank 116, and the fixing solution is stored in each of the two fixing tanks 120.
Rinsing water is stored in 21 and stabilizing liquids are stored in the two stabilizing tanks 122, respectively. If desired,
The bleaching tank 116 and the fixing tank 120 may constitute one bleaching / fixing tank. Therefore, when the photographed negative film F is inserted from the open end side of the developing tank 114 of the photosensitive material processing apparatus 110, these developing tanks 11 which are processing tanks are inserted.
4, bleaching tank 116, two fixing tanks 120, washing tank 121
Then, the negative film F is dipped in the two stabilizing tanks 122 in order and the negative film F is developed. A drying zone 130 is arranged on the open end side of the last stabilizing tank 122, and the negative film F coming out of the stabilizing tank 122 is inserted into the drying zone 130 and dried.

As described above, the developing tank 114 is a slit-shaped tank, and the tank capacity of the developing tank 114 is V.
When the path length, which is milliliters, is Lcm, which is the distance from the position where the negative film F starts to come into contact with the developing solution (the processing tank inlet) to the position where the negative film F is discharged from the developing solution (the processing tank outlet). , V / L is set to 25 or less to reduce the amount of the developer. Note that the tank volume (V) here excludes the volume of the liquid in the circulation system and the volume of the sub-tank or the like that may be used for temperature control of the tank liquid. Further, the fixing tank 116 and the stabilizing tank 120
Similarly, a slit-shaped space is formed inside the other processing baths, and the developing bath 114, the bleaching bath 116, the two fixing baths 120, the washing bath 121, and the two stabilizing baths 122 are joined and arranged respectively. To be done.

Further, in the method of the present invention, the conveying speed of the light-sensitive material is preferably 0.1 m to 5 m per minute, more preferably 0.2 m to 3 m per minute, and 0.
Particularly preferably, it is 3 m and 1.5 m. By using such a processing apparatus, since the processing path 112 of the developing tank 114 having the slit-shaped processing path and having an extremely thin thickness constitutes the transport path of the negative film F, the conventional developing tank 1 is used.
The amount of the developer can be reduced as compared with 14, and a large amount of the replenisher is not required to maintain the characteristics of the developer,
The running cost of the photosensitive material processing apparatus 110 is reduced. Further, by reducing the amount of the developing solution in the above structure, the developing tank 114 for storing the developing solution can be downsized, and accordingly, the photosensitive material processing apparatus 110 can be downsized.
Then, other processing baths such as the bleaching bath 116, the fixing bath 120, the washing bath 121, and the stabilizing bath 122 also operate in the same manner as the developing bath 114. The high silver chloride type photographic light-sensitive material processed by the development processing apparatus 110 is a light-sensitive material composed of a silver halide emulsion having a high content of silver chloride among the silver halides constituting the silver halide emulsion of the light-sensitive material. It is preferable that the silver halide photographic light-sensitive material for photographing comprises a high silver chloride emulsion having a silver chloride content of 80 to 100 mol%.

A second embodiment of a processing apparatus applicable to the photosensitive material processing method of the present invention is shown in the drawings, and the present embodiment will be described based on these drawings. As shown in FIG. 2, in the photosensitive material processing apparatus 10 according to the present embodiment, a U-shaped color developing tank 12 is also provided with a U-shaped bleaching / fixing tank 14 via a connecting member 18A. Connected to each other and further connected in a line while being formed in a U shape.
Three stabilizing tanks 16 connected by C and 18D are connected to the bleach-fixing tank 14 via a connecting material 18B. The color developing solution is stored in the color developing tank 12, and the bleach-fixing solution is stored in the bleach-fixing tank 14.
Rinsing water is stored in each of the three stabilizing tanks 16. Therefore, when the photographed color negative film F is inserted from the open end side of the color developing tank 12 of the light-sensitive material processing apparatus 10, the color developing tank 12, the bleach-fixing tank 14, and the three stabilizing tanks 16 which are processing tanks. Then, the color negative film F is soaked in order to develop the color negative film F. Further, a drying fan 22 is disposed on the open end side of the last stabilizing tank 16, and the color negative film F coming out of the stabilizing tank 16 is inserted into the drying fan 22 and dried.

Of these processing tanks, for example, the developing tank 12 is shown in an enlarged manner in FIG. 3, and a cross section of the color developing tank 12 is shown in FIG. As shown in FIG. 34, the space 1 in the color developing tank 12
2C is formed in a slit shape by the guide portion 12B so that the color negative film F is guided and conveyed by the guide portion 12B which is a part of the inner wall surface of the color developing tank 12. That is, the space 1 in the color developing tank 12
The length of 2C in the width direction is made slightly larger than the width of the color negative film F, and the thickness of the space 12C is made slightly thicker than the thickness of the color negative film F. The space 12C is formed by the guide portion 12B. There is.
Therefore, the guide portion 12B also constitutes the transport path T of the U-shaped color negative film F. Also,
In the wall portion 12A at the central portion in the width direction of the color developing tank 12, a concave portion 26 that is a depression on both upper and lower surfaces in FIG. 4 is formed in a groove shape along the transport path T, and an image of the color negative film F is formed. The inner wall surface of the color developing tank 12 does not come into contact with the portion. As described above, the color developing tank 12 is a slit-shaped tank, the tank capacity of the color developing tank 12 is V milliliter, and the color negative film is fed from the position inside the color developing solution from the position where the color negative film F starts to come into contact with the color developing solution. When the path length, which is the distance to the position where F is discharged, is Lcm, the value of V / L is set to 25 or less to reduce the amount of the color developing solution. Here, the tank capacity excludes the capacity of the circulation system and the capacity of a sub-tank or the like that may be used for controlling the temperature of the color developing solution.

Further, slit-like spaces are similarly formed inside the other processing tanks such as the bleach-fixing tank 14 and the stabilizing tank 16, and the above-mentioned connecting members 18A, 18B, 18 are also formed.
Similarly to the color developing tank 12, C and 18D are also formed in a U shape having a slit-shaped passage therein.
The bleach-fixing tank 14 and the three stabilizing tanks 16 are arranged in an inverted U shape so as to be joined to each other. As shown in FIGS. 3 and 5, in the color developing tank 12, five bulging portions 28, which are spaces bulged at predetermined intervals along the transport path T of the U-shaped color negative film F, are arranged. ing. Inside these bulging portions 28, a pair of conveying rollers 30 as conveying means having drive wheels 30A at both ends are arranged rotatably facing each other. Therefore, when the pair of transport rollers 30 are rotated, the color negative film F is guided to the transport path T in the color developing tank 12 while sandwiching both side portions of the color negative film F between the drive wheels 30A of the pair of transport rollers 30. Will be transported along. A disk-shaped magnet 32, whose magnetic poles are arranged so as to be aligned along the circumferential direction, is attached to one of the drive wheels 30A of the transport rollers 30. A pair of transmission rollers 34 is arranged at a portion outside the color developing tank 12 that faces the magnet 32 of the pair of conveying rollers 30 with the wall portion 12A of the color developing tank 12 interposed therebetween. On the side opposite to the magnet 32, which is one end side of the pair of transmission rollers 34, there is a disk-shaped magnet 36 arranged so that the magnetic poles are arranged along the circumferential direction similarly to the drive wheel 30A of the transport roller 30. Gears 38 that mesh with each other are attached to the other ends of the pair of transmission rollers 34, respectively. Further, a sprocket 42 is attached to the tip of the rotary shaft 40 protruding from the other end of the one transmission roller 34. In addition, the bleach-fixing tank 14 and the stabilizing tank 16
Similarly, a plurality of bulging portions 28 each having a pair of conveying rollers 30 built therein are formed in other processing tanks such as the above, and a pair of transmission rollers 34 having a sprocket 42 are also formed in these bulging portions 28. Each is arranged. A chain 44 is wound around each sprocket 42 throughout the photosensitive material processing apparatus 10, and the chain 44 is driven and rotated by a motor 46 arranged in the photosensitive material processing apparatus 10. As described above, as the chain 44 is rotated by the motor 46, one transmission roller 34 having the sprocket 42 is rotated, and the other transmission roller 34 meshed with the gear 38 is also rotated accordingly. To be done. As a result, the magnets 32 of the conveying roller 30 facing the magnets 36 of the pair of transmitting rollers 34 via the wall portion 12A of the color developing tank 12 are affected by the magnetic force, and the pair of conveying rollers 30 having the magnet 32 form a pair. Will rotate together with the transmission roller 34. Therefore, the chain 44, the pair of transmission rollers 34, and the like constitute a power transmission member that transmits the driving force to the transport roller 30 from outside the color developing tank 12 in a non-contact manner.

On the other hand, as shown in FIG. 4, the color developing tank 12
A pipe 52 is arranged so as to connect a central portion, which is the lowermost portion of the above, to a portion of the color developing tank 12 near the introduction and discharge sides. A pump 54 for sending the color developing solution from the central portion of the color developing tank 12 to the part near the introduction side of the color developing tank 12 and the part near the discharge side of the color developing tank 12 is installed in the middle of the pipe 52. Has been done. Further, a heater 56 for heating the color developing solution sent by the pump 54 to a predetermined temperature is installed at a position of the pipe 52 downstream of the pump 54. The heater 56 has a built-in sensor (not shown) for detecting the temperature of the color developing solution flowing in the pipe 52, and the operating state of the heater 56 can be adjusted based on the temperature of the color developing solution detected by the sensor. ing. Further, the pipe 52 is branched at a position downstream of the heater 56 of the pipe 52 so as to be connected to a portion near the introduction side of the color developing tank 12 and a portion near the discharge side of the color developing tank 12. Pipe 52 on the upstream side of this pump 54
One end side of the pipe 58 is connected to the portion of the above, and the other end side of the pipe 58 is connected to the replenishment tank 60 which stores the replenisher. In the middle of this pipe 58, the replenishment tank 6
A pump 62 for sending the replenisher in 0 into the pipe 52 is arranged. Therefore, the heater 56 is
The replenisher solution sent by will also be heated.

On the other hand, a prescribed amount of replenisher is sucked from the replenisher tank 60 by the replenisher pump 62, and this replenisher is supplied to the color developing tank 12 through the replenishing system pipe 58.
When the replenisher passes through a piping pipe (not shown) in the casting heater 56, it is heated to the same temperature as the temperature of the developer in the color developing tank 12. It should be noted that the piping pipe in the casting heater 56 of the replenishment system has a pipe line length long enough for the replenisher to rise to a predetermined temperature while passing through the piping pipe. The timing of replenishing the replenisher is just before the newly processed color negative film F is inserted into the color developing tank 12, and at this time, the replenishing pump 62 is operated to replenish the prescribed amount of replenisher and further processing is in progress. Replenish as needed. Therefore, during processing of the negative film F, the quality of the developer in the color developing tank 12 is always kept constant. Then, the replenisher is supplied to the upper part of the color developing tank 12 in which the color negative film F is inserted together with or independently of the developer circulating in the color developing tank 12. Although the developer in the color developing tank 12 temporarily increases by the amount supplied with the replenisher, the color developing tank 1 is processed in accordance with the processing of the color negative film F.
The increase from 2 will be discharged. However, an overflow waste liquid port (not shown) may be provided on the exit side of the color negative film F of the color developing tank 12, and the increased amount may be discharged from this overflow waste liquid port and stored in a waste liquid tank (not shown). Further, the replenisher is disclosed in JP-A-4-1288.
The replenishment tank 60, which is a flexible closed container as described in Japanese Patent No. 41, is stored, and the replenishment tank 60 becomes flat as the replenishment liquid inside is sucked out by the replenishment pump 62. Go on. Therefore, air does not enter the replenishment tank 60 to oxidize the replenishment solution, and the initial quality of the replenishment solution in the replenishment tank 60 can be maintained for a long time until it is used up. In the present embodiment, an example of a color negative film has been described, but a black and white film can be processed in the same manner by using the developing tank 12 and the fixing tank 14.

There is no particular limitation on the method of conveying the photosensitive material applied to the processing apparatus according to the method of the present invention, and various known conveying methods shown below can be used. The transport mechanism is known as (1) a so-called drum process in which a photosensitive material is inserted into a liquid filled in a narrow gap by the rotation of a drum, transported, and sent out.
74) p. 45. In this method, the photosensitive material is developed by utilizing the inner wall or the outer wall of the drum, but the outer wall type is preferable from the viewpoint of easy production of the small liquid amount processing tank device. Further, (2) there is known a roller-conveying type processor which conveys a photosensitive material by a counter roller, a zigzag roller or the like by the nip force of the roller, and these are disclosed in Photo Industry February issue (1975) p. 71. This method can be preferably used in the present invention because of the ease of making a small device. Further, as described in JP-A-4-95953, it is still more preferable to use a method of providing a groove through which a photosensitive material passes and controlling a transport route. In this method, generally, a photosensitive material having a thick support is suitable for conveyance, and a thin support preferably has a facing roller type. In the case of a thinner support, it is preferable to install a large number of pairs of opposed rollers or to bond a photosensitive material to the rear end of a thick support (also referred to as a tab leader) for processing. In some cases, a feed mechanism (insertion mechanism) may be provided in the processing tank insertion section. (3) When processing the photosensitive material, the exposed photosensitive material is joined to the rear end of the reader which has been previously passed through the processing tank, and the photosensitive material is processed by driving such as winding up the radar. Although there is a method, this method is generally called cine-type development for photographic light-sensitive materials and leader-trailer transport development for printing light-sensitive materials. These methods are disclosed in March issue of Photographic Industry (1975) p. 70 and same April issue (1
975) p. 40 and May issue (1975) p. 36 and June issue (1975) p. 41. (Refer to FIG. A) These processing methods are methods in which so-called long leaders before and after the photosensitive material are joined and processed, but they are suitable for a case where a large amount of production is required such as a print material. Is. As a transportation method similar to this, (4) an endless leader belt method and an endless chain method are known. This method is from the May issue of Photography Industry (1975).
p. 36 and June issue (1975) p. 41. These methods are not suitable for the present invention because they bring in liquid and bring in much liquid. In the method of (3) described above, the leader is short and not long, and this leader (also referred to as (5) short leader) is moved by a special drive. Used,
It is one of the preferred embodiments that can be applied to the present invention. In this method, (5-1) the short leader is moved by the rotational movement of a belt (timing belt) having a large number of protrusions corresponding to the holes formed in the short leader, and as a result, the photosensitive material is processed. As another method (5-2), there is known a method of processing the photosensitive material by moving the short leader by rotating a gear (sprocket) having a convex portion corresponding to a hole provided in the short leader. For example, the method described in JP-A-4-101139. This method is one of the preferable transportation methods. In particular, the method of transporting with a sprocket is preferable. As a method for processing a small amount of liquid as in the present invention, as a belt conveyance method, JP-A-2-67551 and JP-A-2-103043 have an endless belt method and JP-A-2-67550 and an actual opening flat 2-58744 are magnetic conveyance. As a method, JP-A-1-
154155 is used as a sprocket conveyer.
1139 is known.

The treatment liquid (tank liquid) in the tank of the treatment apparatus used in the treatment method of the present invention is preferably circulated for controlling the temperature and removing suspended matters. The circulation speed depends on the size of the processing tank, but is 0.1 to 3 per minute.
It is 0 liter, preferably 0.2 to 10 liters.
If the circulation is too weak, it becomes difficult to control the temperature,
If it is too strong, the liquid may deteriorate or overflow. In the circulation method of the present invention, it is preferable that the circulation system sucks the tank liquid from the bottom of the processing tank and discharges it to the upper part of the tank. The upper part of the tank is 10c deeper than the liquid surface
It is particularly preferable to discharge to a place within m. Also,
For the purpose of preventing the liquid from overflowing due to the pressure on the upper part of the liquid surface, a method of covering the vicinity of the liquid surface with a wiper blade or the like can be preferably used. At the same time, this wiper blade can also act as a squeegee. As pumps, magnet pumps MD-10, MD- manufactured by Iwaki Co., Ltd.
20, MD-30 and the like are preferably used.

Further, a strong jet is provided in the above circulation system so as to hit the film surface of the (jet stirring) photosensitive material to obtain target photographic characteristics in a short time, accelerate desilvering, wash bath or the like. It is possible to accelerate the washing out of various components in the stabilizing bath. As a method of jet agitation, Japanese Patent Laid-Open No. 3-4144

224382, 5-281688, 7-19943
No. 6, etc. More specifically, the method of jet stirring in each treatment liquid is described in JP-A-62-18346.
A method in which the liquid pumped by a pump is discharged from a nozzle provided facing the emulsion surface described in the item of Example of the invention on page 3, right lower column of No. 0 to page 4 is preferable. As a pump, Iwaki magnet pump MD-1
0, MD-15, MD-20, etc. can be used. The hole diameter of the nozzle is 0.3 to 2 mm, preferably 0.5 to 1.5 mm. Further, it is preferable that the nozzle is opened in a circular shape in a direction perpendicular to the chamber plate surface and the photosensitive material surface as much as possible, but the angle may be 60 to 120 degrees from the conveying direction side, and the shape may be a rectangle or a slit. .. The number of nozzles is 5 to 200, preferably 10 to 100, per liter of tank capacity. Further, if the jet flow strikes a portion of the photosensitive material unevenly, uneven development and residual color unevenness occur. Therefore, it is preferable to sequentially shift the positions of the nozzles so that they do not hit the same place. For example, a row of about 2 to 8 holes is arranged perpendicularly to the carrying direction and the positions thereof are gradually changed at appropriate intervals. If the distance from the nozzle to the photosensitive material is too short, the above unevenness is likely to occur, and if it is too far, the stirring effect is weakened.
It is preferable to be set to 12 mm, and more preferably 1 to 9 mm.
mm. The flow velocity of the liquid discharged from each nozzle also has an optimum range, and is preferably 0.5 to 5 m / sec, particularly preferably 1 to 3 m / sec.

Since the developing process is generally a chemical reaction,
It is necessary to control the temperature during development within a fixed temperature fluctuation range at a specified temperature in order to obtain stable photographic performance. Especially in an automatic processor, since a person does not check the temperature, stable temperature control is important. Such automatic temperature control and homogeneous control in the automatic processor is called temperature control (temperature control). In other words, the temperature control is a function for keeping the liquid temperature of the processing tank at a designated temperature and even.
Therefore, the functions can be divided into a heating part (H), a cooling part (C) (this is not necessary in the case of air cooling), a part for circulating a liquid (J), and a temperature detecting part (S). . S is necessary for temperature control and is preferably installed in the processing tank. (Japanese Patent Application Laid-Open No. 1-170944) There are cases where each combination of the functions of H, C, and J is carried out in a processing tank, a case where they are carried out in another tank, and an intermediate thereof. In the small liquid treatment tank, H and J are preferably at least outside the treatment tank, and H is placed in a sub tank (air opening tank directly connected to the treatment tank), installed in the circulation path, or in the circulation path. It is preferable to install it in a hump tank (air unopened tank: replenishment mixing tank) installed. As a pump used for circulation, an axial flow (propeller) pump, a so-called chemical pump is often used, but a screw pump, a gear pump, a piston pump and the like can also be used. The heater used for the heating part (H) is a stainless steel heater in which nichrome wire is embedded in an insulator, a ceramic heater that utilizes the heat generation of ceramics, a planar heater that utilizes the heat generation of carbon fibers,
There is a cast-in heater (a volume type heater in which the cavity has a cavity in which the temperature-controlling liquid is passed to heat the solution), and the like (Japanese Patent Laid-Open No. 62-246057). The method of incorporating a heater is the most preferable method because the increase of the liquid amount is small. This casting heater is disclosed in JP-A-5-80479 and JP-A-5-20411.
7 has a detailed description.

The circulation flow for efficiently controlling the temperature of the small liquid amount treatment tank is in accordance with the circulation method described above.
As shown in FIG. 1 of 83251, for example, in the case of a U-shaped slit type treatment tank, it is preferable to take out the liquid from the lower part of the U-shape and return it to the upper part of the U-shape on both sides. When returning as shown in this figure, it is most preferable to blow out the liquid with a nozzle having a slit in the width direction of the photosensitive material so that the liquid can be uniformly sprayed over the entire width of the photosensitive material. Further, when the liquid is taken out from the upper part of the U-shape and returned to the upper part of the other U-shape and there is a sub tank, it is generally preferable to take out the liquid from the sub-tank side in order to stabilize the temperature control. In this case, it is advisable to install a blade for preventing liquid spouting on the upper part of the liquid surface on the returning side. For example, the wiper member 78 of FIG. 2 of JP-A-3-257450 is preferable. In this case, if the temperature control is stabilized in the sub tank, it is not necessary to install a blade for preventing liquid outflow in the circulation method of taking out from the upper portion of the U-shape without the sub tank. Control is also required to keep the temperature constant. There are controls such as temperature reduction when the photosensitive material enters the liquid and when it is replenished, control for preventing heating of the heater, energy saving control, outdoor temperature prediction, and the like. For example, JP-A-58-211149 and JP-A-62-2
38556, JP 62-238557, JP 62-
246058, JP-A-1-177542, JP-A1-2
00421, JP-A 1-214850 and the like. As the shape of the processing tank, in addition to the normal type, a sub tank type, a receiver tank type and the like can be mentioned.

It is preferable that the processing apparatus of the present invention has a function of being replenished according to the processing amount of the exposed photosensitive material. Various methods can be adopted as the replenishment method.
For example, as described in JP-A-5-173299, a method of directly replenishing a circulating concentrated solution, JP-A-6-19481.
A method of stocking a concentrated solution in a stock tank once and then replenishing it as described in JP-A No. 64-55560.
As described in JP-A-3-134666, a completion replenisher solution system in which a cartridge of the completion solution is directly replenished to a tank as described in JP-A-64-55561 and 64-55562.

297, 7-169339, etc., and the method of replenishing the solid processing agent and water.

In the treatment apparatus of the present invention, since the opening area of the liquid surface is relatively small, it is preferable to provide a circulation system or a sub tank for replenishment, and replenish at that location. In addition, when replenishing to the circulation system, it is also a preferable method to provide a bulge in a part of the circulation path (hump tank) and replenish to that portion. A replenishing pump is used for replenishing the processing liquid, and a bellows type replenishing pump is preferable.
Further, as a method of improving the replenishment accuracy, it is effective to supplement the diameter of the liquid feeding tube to the replenishment nozzle in order to prevent backflow when the pump is stopped. Preferred inner diameter is 1-8
mm, particularly preferably 2-5 mm.

Various component materials are used in the processing apparatus such as the automatic processor according to the present invention, and preferable materials are described below. As the material of the tank such as the processing tank and the temperature control tank, and the material of the guides of the processing rack and the liquid contact part, modified PPO
(Modified polyphenylene oxide) and modified PPE (modified polyphenylene ether) resin are preferable. Modified PPO
Is "Noryl" manufactured by GE Plastics, modified PP
Examples of E include “Zylon” manufactured by Asahi Kasei Kogyo, “Yupiace” manufactured by Mitsubishi Gas Chemical Co., Ltd., and the like. These materials have excellent chemical resistance to a developing solution, a fixing solution, a bleach-fixing solution and the like. These materials are suitable for injection molding and have an advantage that various hollow molding such as low foam molding, sympress molding, and gas counter pressure molding can be performed. By using these molding methods, it is possible to integrally mold the processing tank and the temperature control tank and the guides and racks with a complicated structure. It became possible to make. It can also be used for large housing members such as covers for automatic processors by engineering blow molding. These materials are common A
Since it has a higher heat resistant temperature than BS, it can also be used as a material for drying parts of an automatic processor. Further, when heat resistance or steel property is required, glass fiber reinforced or filler added grade can be used. Also, ABS (acrylonitrile-butadiene-styrene resin) has chemical resistance to processing solutions (for example, color developing solution, bleaching solution, fixing solution, and bleach-fixing solution), so that it may be partially used in the tank or racks. Can be used for ABS resin from each company such as "Denka" manufactured by Denki Kagaku Kogyo, "Psycholac" manufactured by Ube Industries, Mitsubishi Monsanto Kasei, and Japan Synthetic Rubber can be used. ABS is 80 ℃
It is preferably used in the following environment. Further, ABS is a material suitable for the housing of an automatic processor because it has good moldability by injection molding, has few sink marks during molding, and can be molded with good flatness. This material is also suitable for the processor supply section and cassettes. Further, the olefin resins PE (polyethylene) and PP (polypropylene) are generally used in processing solutions (for example, color developing solution, bleaching solution, fixing solution, stabilizing solution).
Has high chemical resistance to. PE is Showa Denko,
There are many products such as Ube Industries. There are many PP products such as Ube Industries, Chisso, Mitsui Toatsu Chemicals, and Asahi Kasei. It is used as a material for replenishment tanks and waste liquid tanks in automatic processors. Since the material is inexpensive and the large-sized tank can be easily manufactured by hollow molding, it can be preferably used in a portion that does not require high dimensional accuracy. Further, PVC (polyvinyl chloride resin) has excellent chemical resistance, is inexpensive, and can be easily welded, and thus has excellent workability. Many types of PVC are produced by many companies, such as various chemical manufacturers such as the electrochemical industry and Riken Vinyl Industry. Sheet materials extruded from Takiron Industrial "Taquilon Plate" and Mitsubishi Plastics "Hishi Plate" are commercially available, and various modified PVCs are also commercially available and can be easily used. Acrylic-modified PVC is commercially available from in-cylinder plastic “Kyduck” and Sunarrow Chemical. Acrylic modified PVC has a smooth surface and good water repellency, and when used in a tank, it is a suitable material that does not easily cause precipitation of a processing solution (eg, precipitation of a main agent from a color developing solution). As a device for extruding PVC or smoothing the surface of an injection-molded article, it is highly effective to add soybean oil or the like in addition to modified PVC to improve the fluidity during molding. The addition of soybean oil (preferably modified soybean oil) not only smoothes the resin surface and does not impair the quality of the photosensitive material due to scratches, but also
It has the effect of improving the fluidity during molding.

A crystalline polymer can be used as a material of the guide of the processing tank or the processing section in order to prevent the deposition of the color developing agent or the like and to improve the transportability of the photosensitive material. PBT (polyethylene terephthalate), HDPE (ultra-high density polyethylene resin), PTFE (polytetrafluoroethylene resin), PFA (tetrafluoroethylene / perfluoroalkoxyethylene resin), PVDF (polyvinylidene fluoride resin), etc. It is suitable for a guide that comes into contact with a photosensitive material, a liquid interface portion where a processing liquid (for example, a color developing solution) is likely to deposit, and the like. The above-mentioned fluoride is effective even if it is coated on another material such as PPE. As the roller material of the treatment part, PVC (polyvinyl chloride resin), PP (polypropylene), PE (polyethylene), UHMPE (ultra high molecular weight polyethylene), PMP (polymethylpentene), PPS (polyphenylene sulfide), modified P
PO (modified polyphenylene oxide), modified PPE
Thermoplastic resins such as (modified polyphenylene ether) are suitable. Olefinic resins such as PP, PE and PMP can be injection-molded smoothly on the roller surface, and since the specific gravity is small, the rotational load can be reduced, so that the emulsion surface of the conveyed light-sensitive material is not easily scratched and is suitable. They are,
It is often used for drum rollers in the turn section. UHM
Materials such as PE and PTFE (including PFA and PVDF) are suitable for the portion where the photosensitive material slides and the portion where the processing liquid requires water repellency. It has an effect of preventing the photosensitive material from being scratched by the solidified portion of the processing liquid deposited on the roller. A roller provided with these materials on the roller surface (including coating) is suitable for the roller located at the interface of the treatment liquid and the roller for the squeeze portion. PVC is suitable for being easily processed into rollers by extrusion. In addition, a roller having a soft resin portion with low hardness on the surface of the roller can be easily manufactured by double extrusion molding, and it is preferable because the roller can be brought into soft contact with the photosensitive material. PV for rollers that carry
In addition to C, modified PPO, modified PPE, modified PPS, etc. are suitable because they have high steel properties and can withstand high rotational torque. It is preferable to use a glass fiber reinforced or mineral-added strengthening agent such as mica, talc, or potassium titanate in order to further improve the steel property. By adding the reinforcing material, the bending elastic modulus of the roller is improved, creep deformation due to aging can be prevented, and stable conveyance can be ensured without bending the roller after long-term use. Further, by adding an inorganic substance to the resin and molding, the surface can be roughened by the inorganic particles appearing on the roller surface to prevent it from slipping. The surface roughness of the roller can be controlled by adjusting the particle size and the amount of the added inorganic material. A thermosetting resin is suitable for a carrier roller having a small diameter and a photosensitive material having a wide width and a long roller length. PF (phenolic resin), thermosetting urethane resin, and unsaturated polyester resin are preferable. Epoxy resins are also suitable for some processing solutions other than alkaline processing solutions. The PF is preferably a resol type, and Mitsui Toatsu Chemicals “OR-85” is particularly suitable. Graphite may be added for reinforcement. Since this roller can be made thin (for example, the outer diameter is 8 mm), the processing rack can be downsized. As the thermosetting urethane resin, Nippon Unipolymer "Unilon", Dainippon Ink and Chemicals "Pandex", Takeda Chemical Industries "Takenate" and the like are suitable. A roller coated with a fluorine-containing resin is also preferable for preventing the contamination with the developer. Specifically, the resin disclosed in JP-A-4-161955 can be used. An elastomer can be used for a soft roller such as a nip roller. For example, olefin elastomers, styrene elastomers, urethane elastomers, vinyl chloride elastomers and the like are preferable.

Toray and DuPont “Zytel” are suitable as 66 nylon and 6 nylon, and Toray “Rilsan” and Daicel Hüls “Daiamide” are suitable as 12 nylon. Suitable aromatic polyamides include Mitsubishi Gas Chemical's "Renny" polyamide MXD6, and modified polyamides such as Mitsui Petrochemical's "Alen" modified polyamide 6T. PA is preferably a glass fiber reinforced or carbon fiber reinforced grade because it has a high water absorption rate and easily swells in the treatment liquid. Aromatic polyamides have a relatively low water absorption rate and thus are less likely to swell, and high dimensional accuracy can be obtained. In addition, high molecular weight products such as MC nylon obtained by compression molding can obtain sufficient performance without fiber reinforcement. In addition, oil-impregnated nylon resin such as "Polyslider" is also used. Contrary to PA, PBT has a very low water absorption rate, and thus has high chemical resistance to the treatment liquid. Toray and PBT of Dainippon Ink and Chemicals
And Nippon GE Plastics "Barox" are used. PBT is used depending on the site, whether it is a glass fiber reinforced product or an unreinforced product. In order to improve the meshing of gears, it is preferable to use a glass reinforced product and an unreinforced product in combination. As UHMPE, unreinforced products are suitable, and Mitsui Petrochemical's "Lubemer", "Hi-Zex Million", Sakushin Kogyo "New Light", Asahi Kasei "Sunfine", Dai Nippon Printing "Ultra High Molecular Weight Polyethylene UHM"

PEEK is a suitable material that has extremely good chemical resistance and durability against any processing liquid of the developing machine and is an unreinforced product and exhibits sufficient performance.

As the material of the bearing and the like, ultra high molecular weight polyethylene and the like are preferable. Normally, stainless steel (SUS) is used as springs and springs used in processing solutions of automatic processors.
316), titanium pad is used. Plastic springs can be used if the spring or spring cannot be made properly with titanium. For applications where the amount of deformation when a load is applied is small (the critical strain of Hooke's law is 1.6% or less), PBT (eg Nippon GE Plastics “Barox 310” etc.), PP (eg Asahi Kasei “M-1500”) , Etc.), modified PPO (eg Japan GE Plastics “Noril 731J” etc.), modified PP

The bleaching solution, the bleach-fixing solution, and the replenishing amount to the fixing solution used in the present invention are 50 to 2000 ml per 1 m ² of the light-sensitive material. Further, washing water as a post-bath or overflow solution of a stabilizing bath may be replenished as necessary. The processing temperature of the bleaching solution, the bleach-fixing solution and the fixing solution is 20 to 50 ° C, preferably 30 to 45 ° C. The processing time of each step is 10 seconds to 3 minutes, preferably 20 seconds to 2 minutes.

The processing liquid having a bleaching ability used in the present invention is particularly preferably aerated during the processing because the photographic performance is kept extremely stable. Any means known in the art can be used for aeration, and air can be blown into a processing solution having bleaching ability, or air can be absorbed using an ejector. Aeration may be carried out directly in the processing tank, but since the processing machine of the present invention has a small tank capacity, it is a preferred embodiment to provide a subtank and carry out the aeration in the subtank. When blowing air, it is preferable to release air into the liquid through a diffuser having fine pores. Such an air diffuser is widely used as an aeration tank in activated sludge treatment. Regarding aeration, Eastman Kodak Company's Z-121, Eusing Process C-41 3rd Edition (1982), B
The items described on pages L-1 to BL-2 can be used. In the processing using the processing solution having the bleaching ability of the present invention, it is preferable that stirring is strengthened, and the processing is carried out as described in JP-A-3-33847, page 8, upper right column, line 6 to lower left. The contents described in the column and the second line can be used as they are. When aeration is performed in the processing apparatus of the present invention, it is preferable to perform the aeration in a circulation system, a sub tank, or a hump tank provided in the middle of the circulation system.

In the desilvering step, it is preferable that the stirring is strengthened as much as possible. As a specific method for strengthening stirring, the jet stirring method described above is preferable.

The light-sensitive material of the present invention is generally washed with water and / or stabilized after the desilvering process. In the washing and / or stabilizing step of the present invention, it is necessary to adjust the residual thiosulfate concentration of the processed light-sensitive material to 30 to 1500 μmol / m ² . Specifically, it is desirable to adjust the concentration of the thiosulfate in the final bath to be about 0.001 to 0.04 mol / liter. That is, the above-mentioned concentration may be added to the final bath, or when a thiosulfate is used as a fixing component, the amount of replenishment in the subsequent washing and stabilization steps is reduced, and the final bath has the above-mentioned concentration. It is also a desirable embodiment to prepare such a solution. The specific replenishment amount varies depending on the concentration of thiosulfate in the fixing step, the number of baths in the washing step and stabilizing step, etc.
It is about 100 to 1000 ml, preferably about 130 to 700 ml per ² . Regarding the amount of washing water in the washing process, the relationship between the number of washing tanks and the water amount in the multi-stage countercurrent system is as follows.
Motion Picture and Television Engineers Volume 64, P.
248-253 (May 1955). According to the multi-stage countercurrent method described in the literature,
Although the amount of washing water can be greatly reduced, the increase in the residence time of the water in the tank causes a problem that bacteria proliferate and generated floating substances adhere to the photosensitive material. In the processing of the color light-sensitive material of the present invention, as a solution to such a problem, the method of reducing calcium ions and magnesium ions described in JP-A-62-288838 can be used very effectively. Also, isothiazolone compounds and thiabendazoles described in JP-A-57-8,542, chlorine-based disinfectants such as chlorinated sodium isocyanurate, and other benzotriazoles, etc. (1986) Sankyo Publishing, Sanitary Technology Association, "Microbial Sterilization, Sterilization, and Antifungal Technology" (1982) Industrial Technology Association, Japan Society of Antimicrobial and Antifungal Activities, "Encyclopedia of Antimicrobial and Antifungal Agents" (1986) The bactericides described can also be used.

The pH of the final bath in the developing device and the method for processing a light-sensitive material of the present invention can be set to any value, but it is preferably 3.5 to 8, and more preferably 4 to 7. The above pH is preferably set so as to be reflected on the film pH of the processed light-sensitive material, and various buffers can be used for that purpose. Specific examples thereof include acetic acid, malonic acid, succinic acid, malic acid, maleic acid and phthalic acid. The washing water temperature and washing time can be variously set depending on the characteristics of the light-sensitive material, application, etc., but generally 20 to 45 ° C.
At 20 seconds to 5 minutes, preferably at 25 to 40 ° C. for 30 seconds to 3 minutes. Further, the light-sensitive material of the present invention can be processed directly with a stabilizing solution instead of the above-mentioned washing. In such a stabilizing process, JP-A-57-8543 and 58-58 are used.
All known methods described in -14834 and 60-220345 can be used.

The preferable addition amount of these compounds is from 0.001 to 0.02 mol per liter of the stabilizing solution. However, the lower the concentration of free formaldehyde in the stabilizing solution, the less the formaldehyde gas is scattered. From these viewpoints, examples of the dye image stabilizer include N-methylolazoles such as m-hydroxybenzaldehyde, hexamethylenetetramine and N-methylolpyrazole described in JP-A-4-270344, and N, N'-bis (1 4,3,4-triazol-1-ylmethyl) piperazine and the like.

A combination of azolylmethylamine and its derivative such as (-triazol-1-ylmethyl) piperazine is preferable because of high image stability and low formaldehyde vapor pressure. Further, if necessary, ammonium compounds such as ammonium chloride and ammonium sulfite, metal compounds such as Bi and Al, a fluorescent brightener, a hardener, and US Pat.
No. 86,583, and a preservative which can be contained in the above-mentioned fixing solution or bleach-fixing solution, for example, a sulfinic acid compound described in JP-A-1-231105 is also preferable. .

The washing water and / or the stabilizing solution may contain various surfactants in order to prevent unevenness of water droplets during drying of the processed light-sensitive material. Among these, it is preferable to use a nonionic surfactant, and an alkylphenol ethylene oxide adduct is particularly preferable. Octyl, nonyl, dodecyl and dinonylphenol are particularly preferable as the alkylphenol, and 8 to 14 are particularly preferable as the number of moles of ethylene oxide added. It is also preferable to use a silicon surfactant having a high defoaming effect. It is preferable to add various chelating agents to the wash water and / or the stabilizing solution. Preferred chelating agents include aminopolycarboxylic acids such as ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, N, N, N'-trimethylenephosphonic acid, diethylenetriamine-N, N,
Examples thereof include organic phosphonic acids such as N ', N'-tetramethylenephosphonic acid, and hydrolyzates of maleic anhydride polymers described in European Patent 345,172A1.

The overflow solution accompanying the washing with water and / or the supplement of the stabilizing solution can be reused in other steps such as the desilvering step. In the processing using an automatic developing machine or the like, when each of the above processing solutions is concentrated by evaporation,
In order to correct the concentration by evaporation, it is preferable to replenish an appropriate amount of water or a correction solution or a processing replenisher. The specific method for replenishing water is not particularly limited, but among them, a monitor water tank different from the bleaching tank described in JP-A-1-254959 and 1-254960 is installed, and water in the monitor water tank is installed. The amount of evaporation of water in the bleaching tank is calculated from the amount of evaporation of this water, and the bleaching tank is replenished with water in proportion to this amount of evaporation, and JP-A-3-24815.
No. 5, No. 3-249644, No. 3-249645,
The evaporation correction method using a liquid level sensor or an overflow sensor described in JP-A-3-249646 is preferable. Tap water may be used as water for correcting the evaporation of each processing solution, but it is preferable to use deionized water or sterilized water which is preferably used in the above-mentioned washing step.

[0046] For drying method is any method can be selected, it is preferable to use a ceramic hot air heater is preferably min 4m ³ to 20 m ³ as feed air volume, particularly 6 m ³ through 10m ³ preferred.

Next, the photosensitive material used in the developing device and the photosensitive material processing method of the present invention will be described in detail. The high-silver-chloride light-sensitive material used in the method of the present invention comprises a high-silver-chloride emulsion having a silver chloride content of 80 to 100 mol%, and a preferable silver halide composition of the high-silver-chloride light-sensitive material is about It is a silver chlorobromide emulsion containing 50 mol% or less of silver bromide or a pure silver chloride emulsion. Particularly preferred is about 0 mol%
To about 10 mol% silver bromide,
More preferably, it is a silver chlorobromide containing about 0 to about 5 mol% of silver bromide. A silver chloride content of less than 80 mol% is not preferable because it is not suitable for rapid processing.

The silver halide emulsion used in the present invention is:
The emulsion may have any shape such as a regular octahedron, a cubic or a spherical shape, but a tabular emulsion is preferably contained in at least one layer. Particularly, in the tabular high silver chloride emulsion, a tabular silver halide emulsion having a (100) plane as a main plane is preferable. The tabular silver halide emulsion preferably used will be described in detail below. In the tabular silver halide emulsion used in the present invention, the average aspect ratio means the average value of the ratio of the diameter to the thickness of the silver halide grains. That is, it is the average value of the values obtained by dividing the diameter of each silver halide grain by the thickness. Here, the diameter refers to the diameter of a circle having an area equal to the projected area of a grain when the silver halide emulsion is observed with a microscope or an electron microscope. Therefore, the average aspect ratio of 2: 1 or more means that the diameter of the circle is twice or more the thickness of the particles.

In the tabular silver halide grains used in the silver halide emulsion of the present invention, the grain size is 2 times the grain thickness.
It is at least 3 times, preferably 3 to 20 times, more preferably 4 to 15 times, particularly preferably 5 to 10 times. or,
The proportion of tabular silver halide grains in the projected area of all silver halide grains is 50% or more, preferably 70% or more, and particularly preferably 85% or more.

By using such an emulsion, a silver halide photographic light-sensitive material having excellent sharpness can be obtained. The sharpness is excellent because the light scattering by the emulsion layer using such an emulsion is extremely small as compared with the conventional emulsion layer. This can be easily confirmed by those skilled in the art using experimental methods that can be used on a daily basis. The reason why the light scattering of the emulsion layer using the tabular silver halide emulsion is small is not clear, but it is considered that the main surface of the tabular silver halide emulsion is oriented parallel to the support surface.

The tabular silver halide grains have a diameter of 0.
The thickness is 2 to 20 μm, preferably 0.3 to 10.0 μm, and particularly preferably 0.4 to 5.0 μm. The thickness of the particles is preferably 0.5 μm or less. Here, the tabular silver halide grain diameter refers to the diameter of a circle having an area equal to the projected area of the grains. The thickness of the grains is represented by a distance between two parallel planes constituting the tabular silver halide grains.

In the present invention, more preferred tabular silver halide grains have a grain diameter of 0.3 μm or more and 10.0 μm or less.
m or less, the particle thickness is 0.1 μm or more and 1.0 μm or less, and the average aspect ratio (diameter / thickness) is 3 or more and 1
0 or less. If the aspect ratio exceeds 10, the photographic performance may be abnormal when the light-sensitive material is bent, tightly wound, or touched by a sharp object, which is not preferable. More preferably, the particle diameter is 0.4 μm or more.
This is a case of a silver halide photographic emulsion in which grains having an average aspect ratio (diameter / thickness) of 5 μm or less and 0 μm or less account for 85% or more of the total projected area of all silver halide grains.

The tabular silver halide grains used in the present invention are preferably the above-mentioned silver chloride and silver chlorobromide, and may contain tabular silver bromide. The composition distribution in the mixed silver halide may be uniform or localized.

The tabular silver halide grains used in the present invention may have a narrow or wide grain size distribution.
The coated silver amount is 2 to 10 g per square meter of the light-sensitive material.
2 to 6 in high silver chloride light-sensitive materials.
g is preferable, and 2.5 to 5.5 g is most preferable. The silver halide emulsion consisting of tabular silver halide grains used in the present invention is described in the report of Cgnac and Chateau and in "Photographic Em" by Duffin.

The silver halide emulsion consisting of the tabular silver halide grains described above has, for example, 40% by weight or more of tabular silver halide grains in an atmosphere having a relatively high pAg value of pBr of 1.3 or less. To form a seed crystal that has a similar pBr
It is obtained by growing a seed crystal while simultaneously adding a silver and halogen solution while maintaining the value. In this grain growth process, it is desirable to add a silver and halogen solution so as not to generate new crystal nuclei. The size of the tabular silver halide grains can be adjusted, for example, by controlling the temperature, selecting the type and quality of the solvent, and controlling the addition rate of the silver salt used during grain growth and the halide. By using a silver halide solvent, if necessary, during the production of the tabular silver halide grains according to the present invention, the grain size, the grain shape (for example, diameter / thickness ratio), the grain size distribution, and the grain growth. You can control the speed. The amount of the solvent used is 10 in the reaction solution.
The range of ^{-2 to} 1.0% by weight is preferable, and particularly 10 ^-2 to 10
A range of ^-1 % by weight is preferred. In the present invention, the particle size distribution can be monodispersed and the growth rate can be increased with an increase in the amount of the solvent used, but the thickness of the particles tends to increase with the amount of the solvent used.

In the present invention, known silver halide solvents can be used. Examples of frequently used silver halide solvents include ammonia, thioethers, thioureas, thiocyanate salts, and thiazolinethiones. Regarding thioethers, U.S. Patent Nos. 3,271,157 and 3,57

In the emulsion used in the present invention, 50% of the number of silver halide grains preferably contains 10 or more dislocations per grain. The dislocation of tabular grains is described, for example, in J. F. Hamilton, “Photo.Sc
i. Eng. "Vol. 11, p. 57, (1967) and T. Shiozawa," J. Soc. Photo. Sc
i Japan ", Vol. 35, p. 213 (1972), can be observed by a direct method using a transmission electron microscope at low temperature.
Carefully remove the silver halide grains so as not to apply dislocation pressure to the grains, place them on a mesh for electron microscope observation, and cool the sample to prevent damage (eg, printout) by electron beams. In this state, observation is performed by the transmission method. At this time, the thicker the particles, the more difficult it is for the electron beam to pass therethrough. Therefore, it is possible to more clearly observe using a high-voltage electron microscope (200 kV for particles having a thickness of 0.25 μm). . From the photograph of the grains obtained by such a method, it is possible to observe the position and number of dislocations in each grain when viewed from the direction perpendicular to the main plane.

The value of x is preferably 10 ≦ x <100, more preferably 30 ≦ x <98, and further preferably 50 ≦ x <95. At this time, the shape formed by connecting the positions where the dislocations start is close to a shape similar to the particle shape, but may not be a perfect shape and may be distorted. The direction of the transition line is from the center to the side, but it often meanders.

The number of dislocations in the tabular grains used in the present invention is 50% by number of grains containing 10 or more dislocations.
It is preferable that these are present. More preferably, 10

[Table 5]

As is clear from the results shown in Table 5, when the conventional processing machine was used, an increase in yellow stain due to deterioration of the processing solution was observed. Sample 101A using the developing processor of the present invention and using an emulsion outside the scope of the present invention.
When processing (using silver iodobromide emulsion), remarkable processing unevenness occurred. On the other hand, the light-sensitive materials 101B and 1B using the high silver chloride emulsion according to the present invention, using the developing processor of the present invention,
When 01C and 101D were treated, there was almost no generation of treatment unevenness, and the most preferable result was obtained especially when the sample 101B having (100) tabular grains was treated.

(Example 2) Samples 102A and 102 in which APEN of the support in Sample 101A and Sample 101B of Example 1 was changed to a PEN support which was not heat-treated.
B, and samples 103A, 103 modified to TAC support
B was created. An FM signal was recorded on this sample at a speed of 1000 mm / s during the above-mentioned perforation of the photosensitive material by using a head having a head gap of 5 μm and a turn number of 2000 capable of inputting and outputting from the coated surface side of the magnetic recording layer.
The above sample was subjected to overall exposure with 10 CMS and processed in the same manner as each running solution of Example 1, and the processed photosensitive material was evaluated for magnetic reading accuracy and processing scratch generation state. For the magnetic reading accuracy, the ratio of the number of bits in which an error occurred to the number of input bits was calculated. If this error rate is 0.01 or less, there is no practical problem, and if it is 0.1 or more, it is NG. Moreover, the scratches were evaluated in four levels. Table 6 shows the results.

[0150]

[Table 6]

The results shown in Table 6 show that the photosensitive material processed by the comparative processor has a large reading error rate in magnetic recording due to processing stains caused by deterioration of the processing solution.
Further, when the samples 101A, 102A and 103A (using silver iodobromide emulsion) using emulsions outside the scope of the present invention were processed using the developing processor of the present invention, the error rate was slightly improved. However, scratches tend to occur.
On the other hand, when the samples 101B, 102B and 103B using the high silver chloride emulsion using the (100) tabular grains according to the present invention were processed, the error rate was low and the occurrence of scratches was improved. When the photosensitive material 101B using APEN as the support was processed, the occurrence of scratches was remarkably improved, showing the most preferable result. (Example 3) Sample 101 was prepared in the same manner as Sample 101B of Example 1, except that the coating silver amount was changed as shown in Table 7.
E, F and G were created.

[Table 7] Next, the same processing as in Example 1 was carried out in a development processing device having the following specifications. The photosensitive material was transported at a speed of 75 cm / min, and the tank and rack structures were of the conventional short leader type.
