Electrophotographic apparatus employing cylindrical member having space controlling member and press-fitted flange

摘要

A cylindrical member such as a developing roller or photosensitive drum has a sleeve, a flange at the end portion of the sleeve, and a space-controlling member provided at the end portion of the sleeve. The flange is press-fitted into the end portion of the sleeve to be bonded to the sleeve. A space-controlling portion of the space-controlling member is located further from the end of the sleeve than the press-fitted portion of the flange.
