The flange includes a supporting portion supporting an inner peripheral portion of the cylinder within a contact area at which the process units contact the cylinder, and a first supported portion supported by the supporting shaft, with the first supported portion disposed further from the longitudinal end portion of the cylinder than the supporting portion. In addition, a second supported portion is supported by the supporting shaft and is disposed closer to the longitudinal end portion of the cylinder than the supporting portion. A clearance portion is provided between the first supported portion and the second supported portion with respect to a longitudinal direction of the cylinder.
