PURPOSE:To define the replacing time of parts and the kind of the replaced part in the case of reusing a process cartridge next by performing discrimination display to the part which must by replaced in the case of reusing the process cartridge. CONSTITUTION:In the case of reusing the process cartridge for the first time, the discrimination display is performed to the abutting roller 20 of a developing roller 12b to define that the roller 20 should be replaced next. Then, a bearing member 23 having the different diameter of a hole part 23a is color-coded to be selected so as to immediately choose the member 23 fitted to the shaft part 22 of the roller 12b every time the diameter of the shaft part 22 is reduced. Furthermore, a sheet-like seal 25 where the number of replacing times of a cleaning blade 14b is written is stuck on the inner surface or the outer surface of a cleaning device main body 14a every time the blade 14b is replaced, so that the size of a self-tapping screw 24 is immediately known in the case of reusing the cartridge. By performing the discrimination display to the part which must by replaced in the case of reusing the process cartridge, the replacing time of the part and the kind of the replaced part in the case of reusing the cartridge next are defined. |
