Abstract
An electrophotographic photoreceptor is used by being detachably mounted onto an apparatus main body of an electrophotographic application apparatus while being incorporated in a process cartridge. The electrophotographic photoreceptor has a photosensitive drum formed by forming a photosensitive layer containing a photoconductive material on an outer circumferential surface of a cylindrical conductive substrate; and a flange that is fitted to an open end of the photosensitive drum and transmits a rotational driving force from the apparatus main body to the photosensitive drum. In the flange, on a surface thereof receiving the rotational driving force, a driven-side power transmission portion that is configured by a cylindrical body disposed concentrically with respect to a central shaft of the photosensitive drum, and engaging projections are provided.
