摘要

PURPOSE: To perform positioning without being worried about the wear of a rotary shaft and a frame body by performing positioning in a state where the end of the rotary shaft of a processing means acting on an image carrier abuts on a butting part. ;CONSTITUTION: A roller shaft 8a is supported by a 1st bearing member 23 and a 2nd bearing member 24 which can somewhat slide toward a photosensitive drum 7, and attached to a frame body 14. The bearing members 23 and 24 are pressed toward the photosensitive drum by a spring 25 so as to bring an electrostatic charging roller 8 into contact with the photosensitive drum. Namely, the bearing members 23 and 24 are respectively forcibly fitted in the recessed parts 14t of the frames 14s1 and 14s2 of the frame body 14, slidablely attached by regarding the recessed part 14t as a rail, and pressed by a compression spring 25 being a spring member toward the photosensitive drum 7. In such a case, the bearing members 23 and 24 are prevented from dropping from the recessed part 14t by the recessed part 14t1 at the end of the recessed part 14t. By rotatably fitting the roller shaft 8a in the bearing members 23 and 24, the roller 8 is attached.;COPYRIGHT: (C)1994,JPO
