PROBLEM TO BE SOLVED: To prevent unevenness in rotation of a photoreceptor due to unevenness in photoreceptor driving gear when a resin gear is used as the photoreceptor driving gear. SOLUTION: Even when the resin gear is used as the photoreceptor driving gear 11, the unevenness in the rotation of the photoreceptor can be prevented in a simple constitution without any complicated constitution, rotation control or enlargement since the rotation of the photoreceptor driving gear 11 is transmitted to the photoreceptor which is integral with a flange member 12 through an elastic body 13 which is crimped in between a rib 20 in the direction of the diameter of the photoreceptor driving gear 11 and a projecting part 37 of the flange member 12. |
