PROBLEM TO BE SOLVED: To produce a columnar member at a low cost, to decrease electrification noise and further to reduce the disassembly cost by make an electrophotographic photoreceptor have a structure to hold the columnar member through an elastic body. SOLUTION: The columnar member 2 worked to fit to the electrophotographic photoreceptor 1 is inserted in the photoreceptor 1. Then, the elastic body 3 is attached to the member 2, and the member 2 is held in the photoreceptor 1 through the elastic body 3. It is conceivable to form a groove 4 on the member 2 so as to fix the elastic body 3. The groove 4 prevents the elastic body 3 from being deviated when the member 2 is inserted in or taken out from the photoreceptor 1. It is desirable that the elastic body 3 is an O-ring and the member 2 is formed of plastic material whose specific gravity is >=1.5. Especially, it is desirable that the member 2 is made of polybutylene terephthalate resin incorporating >=20% glass fiber. |
