PROBLEM TO BE SOLVED: To keep good rotation accuracy of a photoreceptor drum even if an ambient environmental temperature changes, in a configuration where the photoreceptor drum is rotatably supported by a shaft provided to protrude from a flange of the photoreceptor drum coming into rubbing contact with a bearing part.SOLUTION: A photoreceptor drum 121 is configured of a cylindrical drum 121A, and a flange 121B pressed into a side end of the drum 121A. The flange 121B includes a flange body 60, and a support part 61 provided to protrude outward in a shaft direction from the flange body 60. An SUS-made slide sleeve 70 is pressed into the outer periphery of the support part 61. A slide surface 711 of the slide sleeve 70 is inserted rotatably into a bearing part 80 attached on a housing side of a drum unit. |
