Process cartridge and image forming device |
摘要 |
An image forming device, including a cylindrical photoreceptor drum, an end member having a tubular body which is mounted at an end portion of the photoreceptor drum and which has an outer circumferential surface serving as a sliding surface, and a bearing configured to have a hole which defines an inner peripheral surface that corresponds to a sliding surface, the bearing supporting the tubular body of the end member by inserting the tubular body into the hole, wherein a difference between an outside diameter of a part provided with the sliding surface of the end member and a diameter of the hole of the bearing is equal to or more than 0.06 mm and equal to or less than 0.5 mm. |
