An image bearing member unit for use with an image forming apparatus, includes: an image bearing member including a supported portion onto which a lubricant is applied; a supporting member for rotatably supporting the supported portion; a frame for holding the supporting member; and a spacing maintaining portion provided on the frame or the image bearing member. The spacing maintaining portion is disposed outside the supported portion with respect to a radial direction of the image bearing member, and is disposed inside, with respect to a longitudinal direction of the image bearing member, a region where the supporting member supports the supported portion. When the supporting member is not mounted on the frame, the spacing maintaining portion maintains a spacing between the frame and the supported portion in contact with the image bearing member or the frame. |
