An electrophotographic photoreceptor for incorporation in a process cartridge and removably mounted in the main body of an electrophotographic device. The photoreceptor includes a photosensitive drum having a cylindrical conductive substrate and a photosensitive layer formed on the substrate's outer peripheral surface. The photoreceptor has a gear flange engaged with an open end of the drum, for transmitting rotational driving force from the main body to the drum. A driving force transmitting section, designed to achieve rotational accuracy and rotational strength and realize reduced production costs, includes at least two projected portions inclined in a direction substantially opposite to the rotational direction of the drum, and arranged concentrically about the central axis of the drum. The driving force transmitting section also includes a raised portion, formed on a rotational driving force receiving surface of the gear flange, which reinforces an area between the projected portions.
