PURPOSE:To easily assemble a photosensitive drum with only one shaft member into a processing cartridge by locking a locking part which is integral with a conductive shaft on a second frame. CONSTITUTION:In the case of assembling the photosensitive drum 7 into the frame body 14 of the processing cartridge, the projecting part 7d1 of a gear flange 7d installed on one end in the longitudinal direction of a drum base substance 7a is fitted in the bearing part 14a of the frame body 14 that is a first frame. Then, for the shaft hole 7c4 of a resin helical gear 7c installed on the other end part, a metallic shaft 21(for example iron) is inserted in the hole part 14s of the frame body 14 that is the second frame provided confronting the bearing part 14a and is installed free to turn with respect to the frame body 14 by fixing the shaft 21 on the frame body 14. Also it may be constitued by installing the bearing on the frame body 14 and fitting the projecting part 7d1 of the gear flange 7d in the bearing. |
