PURPOSE: To easily grasp the number of recycling times by providing a number- of-times display part which stores and displays the number of recycling times on the outer surface of a drum supporting body. CONSTITUTION: Every time a recovered photoreceptor unit is disassembled and a photoreceptor 11 is recycled, one of ribs 41 for displaying the number of times is broken so that the number of recycling times may be stored. How many times the photoreceptor 11 is recycled is easily grasped. The rib 41 is provided on the outside surface of a drum driving gear 41, thereby, an end user can't recognize that the photoreceptor 11 is a recycled product. Namely, since the ribs 41 and 41 for displaying the number of recycling times are provided on the outside surface of the gear 14 constituting the drum supporting body 13, the number of recycling times is easily grasped just by counting the number of the bent ribs 41. |
