Abstract
A photosensitive body for electro-photography includes a photosensitive drum, a shaft aligned with a center axis of the photosensitive drum, and a contact member. The photosensitive drum is rotatable relative to the shaft, and the shaft includes a cylindrical shaft body made from an electrically conductive metal, and an electrically conductive metal coating formed on an outer surface of the shaft body. The contact member has an engagement portion in fitting engagement with an inner peripheral surface of the drum body, and a contact portion resiliently and slidingly contacting the shaft to provide an electrical contact between the photosensitive drum and the shaft. The metal coating and at least a surface of the contact portion in direct contact with the outer surface of the shaft body are made from a material identical to each other.
