PROBLEM TO BE SOLVED: To prevent an adhesive from protruding to a surface of a photoreceptor drum while enhancing the precision of an electrophotographic photoreceptor wherein a flange gear provided with a gear for driving is integrally fixed to an end part of the cylindrical photoreceptor drum having a photosensitive layer formed on the surface thereof. SOLUTION: The flange gear is configured so as to have a boss portion allowing a center shaft to be fitted thereto, a disk-shaped web portion, a cylindrical external fitting portion extending from an outer peripheral part of the web portion toward the photoreceptor drum, and a gear portion provided to be integrated with the outer peripheral part of the web portion, and a groove is formed in an inner peripheral surface of the external fitting portion, and the inner peripheral surface of the external fitting portion is externally fitted to an outer peripheral surface of the photoreceptor drum. Furthermore, in the case that an earth plate is attached in the photoreceptor drum, the earth plate is attached so as to come into contact with the inner peripheral surface of the photoreceptor drum in a section wherein the external fitting portion of the flange gear is externally fitted to the outer peripheral surface of the photoreceptor drum.
