構。 A cylindrical photosensitive drum is disposed on which toner is attached to an electrostatic latent image formed on the outer circumferential surface by a follower roller of a developing device that is pressed against the outer circumferential surface, and a rotating shaft is formed protruding from both ends of the photosensitive drum. In a positioning mechanism for a photosensitive drum, which is rotatably supported at the innermost part of a shaft support groove formed in a positioning plate, the longitudinal direction of the shaft support groove of the portion that pivotally supports the rotational shaft of the photosensitive drum is determined. , the direction is perpendicular to the pressing force applied to the photosensitive drum by the follower roller of the developing device, or the longitudinal component of the pressing force in the shaft support groove is directed toward the back of the shaft support groove. A photosensitive drum positioning mechanism characterized by:
