Abstract
An end member is disposed at an end portion of a columnar rotating body mounted on an image forming apparatus body. The end member includes a tubular bearing member and a shaft member held by the bearing member. The shaft member includes a shaft-like rotating shaft which is disposed coaxially to the bearing member, and which rotates around a shaft line with respect to the bearing member to move in a direction of the shaft line, and a tip end member which is disposed coaxially to the rotating shaft, and at which a rotating force receiving member having a tip end provided with an engaging member which engages with a driving shaft of the image forming apparatus body is disposed. A rotating force around the shaft line is transmitted to the rotating force receiving member, the rotating shaft, and the bearing member in order.
