ABSTRACT:
A photosensitive drum includes a cylindrical core which may be fixedly mounted on a rotating shaft and which is comprised of an elastic material and an outer sleeve which is provided on the outer peripheral surface of the core and which includes a supporting layer and a photosensitive layer formed on the supporting layer. A combination of the elastic core and the outer sleeve is constructed such that the drum only deforms locally at a point where an external force is applied and its immediate vicinity while maintaining the other portion virtually unchanged. In one form, the outer sleeve is fixedly mounted on the core, and, in another form, the outer sleeve is detachably mounted on the core. In the latter case, it is so structured that no relative movement takes place between the core and the outer sleeve even if external forces are applied to the drum.
