And, in fixing band 50 sides of driving gear 58, the mode contacted with the inner peripheral surface face with fixing band 50 has formed vibrating part 59.The inner peripheral surface of the periphery of this vibrating part 59 and fixing band 50 is fixing by caking agent etc.And never illustrated electric motor is subject to revolving force and the driving gear 58 that rotates, via this vibrating part 59, to fixing band 50, transmit revolving forces.
In addition, as shown in Figure 9, across fixing band 50 and with press the relative side of pressure roller 52, dispose the described electro-heat equipment 56 relative with the part of fixing band 50.Electro-heat equipment 56 has electromagnetic induction coil (magnet coil) 56A, makes to change in exciting circuit by apply the magnetic field that alternating current produces to electromagnetic induction coil 56A, makes the heating layer of fixing band 50 produce eddy current.This eddy current is because the resistance of heating layer is transformed to heat (joule heating), thereby makes the part heating relative with electro-heat equipment 56 in fixing band 50.That is, in this mode, the part of the fixing band 50 relative with electromagnetic induction coil 56A heating on Zhou Fangxiang.And, before by fixing device 24 conveyance of sheets parts P, make in advance fixing band 50 rotations, so that the integral body of fixing band 50 reaches for making the fixing temperature of toner image on paper parts P.
And, the relative mode with the inner peripheral surface of the fixing band 50 with by electro-heat equipment 56 heating parts, the circular-arc heat generating components 60(auxiliary heater that configuration is heated fixing band 50).
By making these heat generating components 60 heatings, fixing band 50 is heated, thereby compared with the situation that does not there is heat generating components 60, can make fixing band 50 arrive at short notice fixing temperature.
(wanting section's method)
Below, heat generating components 60 is described.
As shown in Figure 3, Figure 4, heat generating components 60 has: a pair of insulation film 62, and it extends to a direction (arrow B direction in figure), by the polyimide resin moulding; And metallic heating body 64, it is by these a pair of insulation film 62 clampings.And the thickness of each insulation film 62 is 50[μ m].
In addition, in each figure, for ease of understanding the structure of heat generating components 60, be recited as the flat heat generating components 60 be shaped to before circular-arc.In the explanation of back, the heat generating components 60 of also take describes as tabular.

(metallic heating body)
Below, metallic heating body 64 is described.
As shown in Fig. 1 (B), the position 66 of crawling has: the projection 70 of convex; And otch 72, it departs to the inside identical amount (side-play amount is same amount: be 70[μ m in the present embodiment]) with respect to projection 70 and forms.And, in the mode of being surrounded by this otch 72, form incision tract 73.
And otch 72 has: circular-arc leading section 72A; And a pair of line part 72B, its from this leading section 72A until base end side (downside figure) with linearity, extend.
And the internal diameter of this leading section 72A (R1 shown in figure) is 80[μ m], a pair of line part 72B extends to the orthogonal directions (arrow C direction in figure) with a described direction (arrow B direction in figure) quadrature.
(manufacture method of metallic heating body)
Below, as an example of the manufacture method of metal sheet, the manufacture method of metallic heating body is described.
As Fig. 7 (A) (B) as shown in, at first, in the resist working procedure of coating, at thickness 50[μ m] the example of sheet material 150(metal sheet of SUS304) two surfaces, with thickness 1[μ m] coating positive photoresist 152.
Then, as shown in Fig. 7 (C), in exposure process, make the film base plate 154 that is formed with etched pattern be close on the sheet material 150 that is coated with photo-resist 152 and fix.And exposed to film base plate 154, the pattern 160(that will crawl is with reference to Fig. 1 (A)) photo-resist 152 is burned.In addition, about crawling pattern 160 as described later in detail.
Then, as shown in Fig. 7 (D), in the video picture operation, use image-developing liquor to carry out the video picture processing to the crawl sheet material 150 of pattern 160 of exposure transfer printing on photo-resist 152.Thus, the photo-resist 152 in the zone of having exposed is dissolved in image-developing liquor, and photo-resist 152 forms in the mode of S shape.
Then, as shown in Fig. 7 (E), in etching work procedure, sheet material 150 is immersed in to etching solution (in the present embodiment, as an example, be solution of ferrous chloride) in, or spray (spray) etching solutions to sheet material 150, thereby the exposed portions serve of the sheet material 150 that exposes by video picture is carried out to etching.
Then, as shown in Fig. 7 (F), in the resist stripping process, utilize sodium hydroxide solution, the photo-resist 152 be coated on sheet material 150 is removed.Thus, manufacture metallic heating body 64.
(pattern crawls)
Below, for the crawl pattern 160 burned to photo-resist 152, describe.
In Fig. 1, the crooked position of the pattern 160 that crawls is shown.For by wet etching, forming the pattern 160(etched pattern that crawls by the projection 70 shown in the two dot chain line of Fig. 1 (A) and otch 72), must be to the inboard skew of the edge of otch 72, and be offset to the outside of the edge of projection 70.Thus, the pattern 160 that crawls has: the inboard pattern 160A that crawls, and skew is to the inside compared in its edge with otch 72; And the outside pattern 160B that crawls, skew (solid line in figure) is laterally compared in its edge with projection 70.
In etching work procedure, etching solution is invaded the inside of the pattern 160 that crawls, and sheet material 150 is carried out to etching (so-called side etching method).Thus, otch 72 forms greatlyr with respect to the inboard pattern 160A that crawls, and in addition, projection 70 forms littlely with respect to the outside pattern 160B that crawls.In addition, photo-resist is called to the resist side-play amount with respect to the amount of edge (two dot chain line shown in Fig. 1 (the A)) skew of the product in design.
And, in the present embodiment, the resist side-play amount of the leading section 72A in otch 72 (E size in figure) is different from the resist side-play amount (F size in figure) of line part 72B, radius-of-curvature based on leading section 72A, be made as less than the resist side-play amount of line part 72B.Its reason is, Yi Bian, Yi Bian side etching spreads intrusion (carrying out) towards periphery, therefore, in leading section 72A, the intrusion amount of side etching is compared less with line part 72B.
; as shown in Figure 2 (A) shows, if make the resist side-play amount, at leading section 72A and line part 72B place, be identical amount (distance), as shown in Fig. 2 (B); the otch amount (solid line) of the leading section obtained after etching work procedure, will be less than the otch amount (dotted line) of the leading section in design.
On the other hand, as shown in Fig. 1 (A), the resist side-play amount of circular-arc arc sections 70A in projection 70 (G size in figure) is different from the resist side-play amount (H size in figure) of the line part 70B of linearity in projection 70, radius-of-curvature based on arc sections 70A, its side-play amount of resist than line part 70B is large.
Its reason is, due to side etching, from invading on every side, therefore at arc sections 70A place, the intrusion amount of side etching is compared many with line part 70B.
; as shown in Figure 2 (A) shows; if make the resist side-play amount become identical amount (distance) at arc sections 70A and line part 70B place,, as shown in Fig. 2 (B), the overhang of the arc sections obtained after etching work procedure (solid line) is less than the overhang (dotted line) of the leading section in design.
In addition, as shown in Fig. 1 (A), the resist side-play amount (F size in figure) of the line part 72B of the resist side-play amount of the line part 70B of projection 70 (H size in figure) and described otch 72 is identical condition for the intrusion of side etching, therefore becomes identical amount.
Measuring different reasons for the intrusion of side etching here, describes particularly.
Mean shape of product with solid line in Fig. 8, with two dot chain line, mean photo-resist.The line length of the edge of photo-resist is made as to overall length L, in the situation that to line part (with reference to Fig. 8 (A)) carry out moulding situation, to recessed fillet part (with reference to Fig. 8 (B)) carry out moulding situation, dome bight (with reference to Fig. 8 (C)) carried out to moulding, the intrusion amount of side etching can produce difference.Its reason is, the amount (the oblique line area S shown in each figure) that corrodes mother metal by etching is identical.
As mentioned above, because the erosion amount (the oblique line area S shown in each figure) of mother metal is identical, therefore, the intrusion amount of the side etching in recessed fillet part (the size Q of Fig. 8 (B)), compare little with the intrusion amount (the size P of Fig. 8 (A)) of side etching in line part.
On the other hand, the intrusion amount of the side etching in the dome bight (the size R of Fig. 8 (C)), compare greatly with the intrusion amount (the size P of Fig. 8 (A)) of side etching in line part.
Then, to the resist side-play amount of the leading section 72A that determines otch 72, and the order of the resist side-play amount of the arc sections 70A of projection 70 describe.
At first, the curve shown in Fig. 6 is described.In Fig. 6, the relation between the radius-of-curvature of the leading section 72A of simulation otch 72 and the amount of not reaching of locating in front position (cutting maximum positions), illustrate this result with curve.
The transverse axis of the curve shown in Fig. 6 means the radius-of-curvature [μ m] of the leading section 72A of otch 72, and the longitudinal axis is illustrated in thickness of slab 50[μ m] the situation of sheet material of SUS304 under, side etching do not arrive the not arrival amount [μ m] of product end.
Specifically, in the situation that the resist side-play amount is 35[μ m], mean with respect to this 35[μ m], the not arrival amount at leading section 72A place [μ m].That is, not arrival amount 10[μ m] the intrusion amount of side etching in situation is, from resist side-play amount 35[μ m] deduct the amount of not reaching 10[μ m], be 25[μ m].Known according to this curve, [μ m] is less for the radius-of-curvature of leading section 72A, and the amount of not reaching is larger.
In the present embodiment, the resist side-play amount of line part 72B is made as to 35[μ m].For leading section 72A, because radius-of-curvature is 80[μ m], therefore, according to Fig. 6, the amount of not reaching is 12.1[μ m].Thus, in front position (the position Y shown in Fig. 1 (A)), locate, the resist side-play amount of leading section 72A becomes 22.9[μ m] (35-12.1).
Below, the curve shown in Fig. 5 is described.Relation between the radius-of-curvature of the arc sections 70A of projection 70 and the amount of retreating that front position (the most outstanding position) is located is simulated, and Fig. 5 illustrates this result with curve.
The transverse axis of the curve shown in Fig. 5 is made as the radius-of-curvature [μ m] of the arc sections 70A of projection 70, and the longitudinal axis is made as in the situation that thickness of slab 50[μ m] the sheet material of SUS304, the amount of retreating that the product end retreats due to side etching [μ m].
Specifically, in the situation that the resist side-play amount is made as to 35[μ m], mean with respect to this 35[μ m], the amount of retreating at arc sections 70A place [μ m].That is, the amount of retreating 10[μ m] situation under the intrusion amount of side etching be, by resist side-play amount 35[μ m] add the amount of retreating 10[μ m], be 45[μ m].Known according to this curve, [μ m] is less for the radius-of-curvature of arc sections 70A, and the amount of retreating is larger.
In the present embodiment, with line part 72B similarly, the resist side-play amount of line part 70B is made as to 35[μ m].For arc sections 70A, because radius-of-curvature is 150[μ m], therefore, according to Fig. 5, the amount of retreating is 6.4[μ m].Thus, for the resist side-play amount of arc sections 70A, in front position (the position Z shown in Fig. 1 (A)), locating, is 41.4[μ m] (35+6.4).
(wanting the effect of section's method)
As mentioned above, the manufacture method of related metallic heating body according to present embodiment, the resist side-play amount of the arc sections 70A in projection 70, the radius-of-curvature based on arc sections 70A, be made as larger than the resist side-play amount of line part 70B.The shape of product of the projection 70 formed by wet etching thus, approaches design load.In addition, the resist side-play amount of the leading section 72A of otch 72, the radius-of-curvature based on leading section 72A, be made as less than the resist side-play amount of line part 72B.The shape of product of the otch 72 formed by wet etching thus, approaches design load.
In a word, because the shape of product of metallic heating body 64 approaches design load, therefore can reduce due to the different fraction defectives that cause of shape.
In addition, because the shape of product of metallic heating body 64 approaches design load, therefore can be had good uniformity and be approached the thermal value of the metallic heating body 64 of prescribed value (design objective value).
In addition, for specific embodiment, at length describe the present invention, but the present invention being not limited to embodiment, within the scope of the invention, can realizing other numerous embodiments, is clearly to those skilled in the art.For example, in the above-described embodiment, manufacture method for the metallic heating body with projection 70 and otch 72 is illustrated, but as Figure 12 (A) (B) as shown in, sometimes in the projection 90 of metallic heating body 88, do not form the arc sections shown in present embodiments, and form as shown in the embodiment circular-arc leading section 92A and line part 92B at otch 92.In this case, can only to otch 92, use the thought of present embodiment.
Specifically, the resist side-play amount of the leading section 92A of otch 92 (J size in figure), different from the resist side-play amount (K size in figure) of line part 92B, the radius-of-curvature based on leading section 92A, be made as less than the resist side-play amount of line part 92B.
In addition, in the above-described embodiment, for the manufacture method of metallic heating body that there is projection 70 and be formed with the otch 72 of line part 72B, be illustrated, but as Figure 13 (A) (B) as shown in, existence does not form the line part shown in present embodiment at the otch 102 of metallic heating body 98, but only form the circular-arc leading section 102A shown in present embodiment at otch 102, and only form the situation of arc sections 100A in projection 100.In this case, can use to the arc sections 100A of the leading section 102A of otch 102 and projection 100 thought of present embodiment.
Specifically, the resist side-play amount of the leading section 102A of otch 102 (L size in figure) is different from the resist side-play amount (M size in figure) of arc sections 100A, the radius-of-curvature of radius-of-curvature based on leading section 102A or arc sections 100A, be made as less than the resist side-play amount of arc sections 100A.
In addition, in the above-described embodiment, the manufacture method of metallic heating body with circular shape of take is illustrated as example, but the manufacture method of metal sheet that also can present embodiment is related is for the manufacture method of other metal sheets with circular shape.
In addition, in the above-described embodiment, the sheet material of the SUS304 of used thickness 30 μ m is illustrated, but also can use the metal sheet of other thickness and material.
