摘要:
A disclosed photoconductive drum includes a mechanism where, when the sleeve inner circumferential surface pressing member is in contact with the inner circumferential surface of the photoconductive sleeve member, a displacement of the first end surface member with respect to the photoconductive sleeve member in the center line direction leads to increasing a pressing force applied from the sleeve inner circumferential surface pressing member to the inner circumferential surface of the photoconductive sleeve member.
