PROBLEM TO BE SOLVED: To provide a process cartridge configured to separate a charging roller from a photoreceptor with a simple mechanism, while preventing an increase in size of a process cartridge or the image forming device.SOLUTION: A process cartridge 50 includes a photoreceptor 1, a charging roller 2, a support 21 for rotatably supporting a rotary shaft 2a of the charging roller 2, and a biasing member 25 for biasing the support 21 toward the photoreceptor 1. The support 21 includes a bearing part 21h, a contact part 21a, and a drive receiving part 21b. At the start of using the process cartridge 50, a rotating force of the photoreceptor 1 is transmitted to the drive receiving part 21b. Therefore, the support rotates around the rotary shaft of the charging roller 2 from a first position for serving as a spacer to a second position for serving as a bearing. In the first position, the support is pressed in a direction away from the photoreceptor 1. In the second position, the support is pressed in a direction toward the photoreceptor 1. |
