PROBLEM TO BE SOLVED: To obtain a photoreceptor drum, having little variance in an eccentric direction from a drum body and a flange member having errors in terms of manufacturing accuracy. SOLUTION: This photoreceptor drum 12 is constituted of the drum body 14 and two flange members 16 and 18. The body 14 is constituted of a cylinder 1402 where fitting holes 1406 are formed at both ends and a photoreceptive layer 1404, formed on the outer peripheral surface of the cylinder 1402, and the center C2 of the outer peripheral surface of the body 14 is made eccentric from the center C1 of the hole 1406. The members 16 and 18 are equipped with annular plate parts 1602 and 1802 and bearing parts 1604 and 1804, and the center C4 of the plate parts 1602 and 1802 is eccentric from the center C3 of the bearing parts 1604 and 1804. The eccentric direction F1 of the body 14 and the eccentric direction F2 of the members 16 and 18 are set nearly in the same direction, and the plate parts 1602 and 1802 are press-fit and fixed in the hole 1406. |
