ABSTRACT:
A photosensitive body for electro-photography includes an electrically conductive photosensitive drum, an electrically conductive shaft, and an electrically conductive contact member. The photosensitive drum is rotatable relative to the shaft. The shaft includes a cylindrical shaft body and a metal coating formed on the outer surface of the shaft body and made from an electrically conductive material having an ionization tendency lower than that of a substrate of the shaft body. The contact member has an engagement portion in fitting engagement with an inner peripheral surface of the drum body, and has a contact portion resiliently and slidingly contacting the shaft to provide an electrical contact between the photosensitive drum and the shaft. The contact portion is made of a material whose ionization tendency is higher than that of the metal coating.
