PROBLEM TO BE SOLVED: To provide a cylindrical electrophotographic photoreceptor capable of being smoothly driven over a long period, in which a flange equipped with a gear part being excellent in dimensional accuracy, and free from deformation is attached. SOLUTION: In this cylindrical electrophotographic photoreceptor 1 in which the flange 3 provided with a gear for a rotary drive is attached in the end part of the photoreceptor drum 2, the flange 3 is constituted so that a gear is formed on a periphery of an annular body, an annular groove in a concentric circular shape with regard to the gear is grooved on one side wall, and, the drum fitting part in cylindrical shape provided with the periphery connected to the inside peripheral wall surface of the annular groove is provided successively and moreover, the drum end part is fit in the above annular groove. |
