PROBLEM TO BE SOLVED: To obtain a photoreceptor for which the quantity of synthetic resin material to be used is made as small as possible with simple constitution without lowering mechanical strength by driving and rotating a supporting body around an axial line while the coupling member of a driving means is meshed with a part to be driven, provided at the end in the axial direction of the supporting body. SOLUTION: The supporting body 2 is made cylindrical and the part to be driven 9 is provided at the end in the direction of the axial line of the supporting body 2. Plural projecting parts 18 and recessed parts 19 are alternately adjacently formed in a peripheral direction on the part to be driven 9, and the projecting parts 18 and the recessed parts 19 are formed to face to the outside in the direction of the axial line 16. The coupling member 72 of the driving means 71 has a driving recessed part 20 and a driving projecting part 21 meshed with the projecting part 18 and the recessed part 19, and has the axial line on a straight line with the axial line 16 of the supporting body 2 in an attached state. In such a meshed state, the supporting body 2 is driven and rotated around the axial line 16. Thus, the photoreceptor where the increase of the quantity of the synthetic resin to be used is restrained to be as small as possible is obtained with simple constitution without lowering the mechanical strength. |
