Information is read by the provided reading contact 84. Then, information is transmitted to the control device 5 built in the color printer 10. The memory 83 may be provided on the side surface of the process cartridge 30 or the like.

(Process cartridge operation)
Next, the operation of the process cartridge 30 will be described. In the developing unit section 40, the supply device 44 conveys the developer from the back side to the near side in the drawing in the supply area 46, and the stirring device 45 develops the developer from the near side to the far side in the drawing in the stirring area 47. Transport. Since the supply area 46 and the agitation area 47 are connected to each other at both ends in the longitudinal direction as described above, the developer is circulated and conveyed while being agitated in the housing 41. At this time, the carrier has a positive charging polarity, and the toner has a negative charging polarity. For this reason, the toner and the carrier in the developer are rubbed with each other as they are stirred and conveyed, the carrier is charged positively, and the toner is charged negatively.

  When the developer to be stirred and conveyed is conveyed to the supply area 46 facing the developing roll 43, the carrier in the developer is magnetically attracted by the magnetic force of the magnetic pole provided on the magnet roll 43a, and the developing sleeve Carriers are transferred and deposited on 43b. At this time, since the negatively charged toner is electrostatically adsorbed to the positively charged carrier, the toner is transferred and attached to the developing sleeve 43b along with the carrier. Therefore, the developer including toner and carrier adheres on the developing sleeve 43b. The developer on the developing sleeve 43b is conveyed while being held on the developing sleeve 43b by the rotation of the developing sleeve 43b and the magnetic force of the magnet roll 43a, and is regulated to a predetermined thickness by the layer thickness regulating member 50. Then, it is conveyed to the opening 42 facing the photosensitive drum 14.

  A predetermined developing bias is applied to the developing sleeve 43b from a power source (not shown), whereby the developing sleeve 43b is formed on the photosensitive drum 14 from the developer layer on the developing sleeve 43b in a developing region close to the photosensitive drum 14. The toner is transferred to the electrostatic latent image and visualized (toner image). The developer layer on the developing sleeve 43b that has passed through the opening 42 of the housing 41 and completed development is separated by the repulsive magnetic field formed between the magnetic poles of the same polarity of the magnet roll 43a and falls to the supply area 46. The developer that has fallen into the supply area 46 is again agitated and conveyed by the supply device 44 and the agitation device 45 to be used for the next developing action.

  As described above, in the developing unit section 40, the electrostatic latent image on the photosensitive drum 14 is developed and visualized, so that the ratio of toner to the developer (toner density) gradually decreases. . Therefore, in this embodiment, new toner is replenished from the main toner replenishment unit 60 to the developing unit 40 whose toner density has decreased. Toner is replenished from the main toner replenishing unit 60 to the developing unit 40, the toner in the toner storage chamber 61 of the main toner replenishing unit 60 is passed through the toner carry-in port 67 by the first agitator 62 and the second agitator 63. The toner is supplied to the toner replenishing chamber 64, and the toner in the toner replenishing chamber 64 is transported by the replenishing device 65 and supplied to the stirring area 47 of the developing unit 40 through the toner replenishing port 68. The toner replenished to the stirring area 47 of the developing unit 40 in this way is stirred and conveyed by the stirring device 45 together with the developer already present in the developing unit 40, and the developer and newly supplied toner and Is conveyed from the agitation zone 47 to the supply zone 46 in a state of being agitated and mixed, and used for development.

  When the toner stored in the toner storage chamber 61 is supplied to the developing unit 40 and decreases, the toner stored in the toner storage chamber 61 is supplied from the sub toner supply unit 35 via the connection passage 66. In this way, as the toner in the developing unit 40 is consumed, toner is supplied from the main toner supply unit 60, and the main toner supply unit 60 is supplied from the sub toner supply unit 35. Thus, the toner concentration in the developer in the developing unit 40 can be maintained at a predetermined value until the life of the process cartridge 30 is exhausted.

(Configuration of polymerization tape portion 80 and protective member)
Next, the superposition | polymerization tape part 80 and the protection member 100 are demonstrated with reference to drawings. FIG. 6 is an external perspective view showing a state in which a protective member is attached. FIG. 7 is an external perspective view of the state in which the protective member is attached as seen from the back side.

  As shown in FIG. 4, the developer seal tape (blocking means) 81 blocks the opening 71 of the developer chamber 70 in which the developer is accommodated. The developer seal tape 81 has a length that is at least twice that of the opening 71 in the longitudinal direction of the opening 71, the tip of the developer seal tape 81 corresponds to one end of the opening 71, and is folded back at the other end of the opening 71. It is. The free end of the developer seal tape 81 reaches the outside from the side end of the upper housing 41b.

  As shown in FIG. 4, the toner seal tape (blocking means) 82 blocks the toner supply port 68 of the toner storage chamber 61 in which toner is stored. The toner seal tape 82 is affixed to the periphery of the toner supply port 68. The tip of the toner seal tape 82 corresponds to one end of the toner replenishing port 68 and is folded back at the end of the toner replenishing port 68. The free end of the toner seal tape 82 reaches the outside of the lower housing 41a.

  The polymerization tape portion 80 is a member in which a toner seal tape 82 is overlapped with a developer seal tape 81 with an adhesive surface facing each other. In the polymerization tape portion 80, the developer seal tape 81 and the toner seal tape 82 are bonded together at a free end reaching the outside of the housing 41, and are combined into one sheet. The polymerization tape portion 80 removes the developer seal tape 81 and the toner seal tape 82 by being pulled.

  As shown in FIGS. 6 and 7, the superposed tape portion 80 is disposed on the protective member 100. The polymerization tape unit 80 is fixed to the process cartridge 30 and the protection member 100 by an adhesive tape 91 attached to the process cartridge 30. Further, the connection member 92 is directly bonded and connected to the polymerization tape portion 80.

It is possible to set the toner cartridge 30 to the same size as when the toner cartridge 30 is not attached. As a result, even when the process cartridge 30 is inserted with the developer seal tape 81, the toner seal tape 82, and the protective member 100 attached to the process cartridge 30, there is no need to change the design of the main body 10a.

  Furthermore, the process cartridge 30 can be inserted into the mounting opening 10b of the main body 10a with the developer seal tape 81, the toner seal tape 82, and the protective member 100 attached. That is, the process cartridge 30 can be bundled and conveyed in the image forming apparatus 10. As a result, the main body 10a of the color printer 10 and the process cartridge 30 can be transported in a smaller space than when transported separately.

  The protection member 100 includes a protection unit (protection unit) 110 and a blocking unit (blocking unit) 120. That is, the protection unit 110 and the blocking unit 120 are connected to each other by integrally forming the protection unit 110 and the blocking unit 120. Therefore, when the protection unit 110 is to be removed, the blocking unit 120 is also removed. As a result, forgetting to remove is prevented. The protection member 100 protects the photosensitive drum 14 and the memory 83 when the process cartridge 30 is bundled and transported in the main body 10 a of the color printer 10.

  The protection part 110 is formed in a sheet shape. The protection unit 110 is provided so as to cover the periphery of the process cartridge 30. The protection part 110 is disposed under the polymerization tape 80. Therefore, when removing the protective part 110, the superposition | polymerization tape 80 is removed first. Further, the protection unit 110 is disposed on the blocking unit 120. The protection part 110 has a first opening 111, a second opening 112, and an insertion part 113. The protection unit 110 protects the photosensitive drum 14.

  A connection member 91 is inserted into the first opening 111. That is, the overlapping tape part 80 and the protection part 110 are connected via the connection member 91. Therefore, if the protective member 100 having the protective portion 110 is removed without removing the superposed tape portion 80, an operator (not shown) forgets to remove it. As a result, forgetting to remove is prevented.

  An insertion portion 113 is inserted into the second opening 112. By inserting the insertion portion 113 into the second opening 112, the protection portion 110 is fixed to the toner cartridge 30.

  The blocking part 120 is formed in a sheet shape. The blocking unit 120 blocks the electrical connection between the main body 10 a and the memory 83 via the reading contact 84. Further, the blocking unit 120 protects the memory 83. That is, the blocking unit 120 is formed in a shape that protects the memory 83.

  The blocking unit 120 is disposed on the back side of the process cartridge 30. In addition, the blocking unit 120 is disposed below the protection unit 120. Therefore, when removing the blocking unit 120, the protection unit 120 is first removed. Further, since the protection unit 110 is fixed to the toner cartridge 30, if an attempt is made to remove the blocking unit 120 without removing the protection unit 110, an operator (not shown) forgets to remove the protection unit 110. As a result, forgetting to remove is prevented. That is, first, the developer seal tape 81 is removed, and then the protective part 110 is removed, and then the blocking part 120 is removed.

  In addition, not only this embodiment but it is good also as embodiment which fixes and connects the superposition | polymerization tape 80 to the protection member 100 so that the superposition | polymerization tape 80 may be pulled when the protection member 100 is removed. In addition, the developer seal tape 81, the toner seal tape 82, and the protective member 100 are not limited to be attached to the process cartridge, but may be an embodiment that can be attached to the toner cartridge.

(Removal operation of polymer tape and protective member)
Next, the removal operation of the superposed tape part 80 and the protective member 100 will be described with reference to the drawings.

  When transporting the color printer 10, the process cartridge 30 is inserted into the mounting opening 10 b of the main body 10 a with the developer seal tape 81, the toner seal tape 82, and the protective member 100, and is transported together with the color printer 10. Is done. That is, the color printer 10 is transported with the process cartridge 30 in a state in which the developer seal tape 81, the toner seal tape 82, and the protective member 100 are attached. Thereafter, the process cartridge 30 is taken out from the color printer 10 at a transport destination by an operator (not shown).

  First, the connection member 92 is extracted from the first opening 111, and the connection member 92 is pulled. When the connecting member 92 is pulled, the adhesive tape 91 is peeled off from the process cartridge 30, and the polymerization tape portion 80 is pulled via the adhesive tape 91. Then, the developer seal tape 81 and the toner seal tape 82 are removed from the process cartridge 30.

  Next, the insertion portion 113 is extracted from the second opening 112, and the insertion portion 113 is pulled. When the insertion portion 113 is pulled, the protection portion 110 and the blocking portion 120 are connected, so that the protection portion 110 and the blocking portion 120 are removed from the process cartridge 30.

  After the developer seal tape 81, the toner seal tape 82, and the protective member 100 are removed, the process cartridge 30 is reinserted and mounted in the mounting opening 10b of the main body 10a. Then, the color printer 10 is activated. At this time, the control device 5 determines whether or not all of the blocking portions 120 of the process cartridges 30Y, 30M, 30C, and 30K have been removed from the connection status between the main body 10a and the memory 83. If it is determined that it has not been removed, a message prompting removal work such as the blocking unit 120 is displayed and the color printer 10 cannot be used. On the other hand, if it is determined that the color printer 10 has been removed, the color printer 10 is put into a usable state.

  As described above, since the blocking unit 120 is finally removed, the developer seal tape 81, the toner seal tape 82, and the protection member 100 are removed only by determining whether or not the blocking unit 120 has been removed. It is possible to confirm whether or not

  The present invention can be used for an image forming apparatus such as a color printer, a FAX, a color copying machine, and an apparatus having these functions.
