Mounting member, cylinder member, and image forming apparatus

An image forming apparatus comprising:

• a cylinder member which conveys a recording medium;
• and
• a transfer member, comprising a counter roller, that comes into contact with the cylinder member through an intermediate transfer body, comprising a transfer belt, and transfers an image formed on the intermediate transfer member to the recording medium conveyed by the cylinder member,
• wherein the cylinder member, comprises:
• a cylinder body, having a substantially circular cross-section, the cylinder body including a recessed portion formed along an axial direction and configured to rotate in a circumferential direction and to make an opening edge portion of the recessed portion on an upstream side in a rotation direction abut against another member by rotation;
• and
• a mounting member which is wound around an outer peripheral surface of the cylinder body except for the recessed portion,
• wherein the mounting member comprises:
• a rectangular sheet member;
• and
• an attachment portion having a first surface bonded to one end portion of a reverse surface of a downstream side portion of the sheet member in the traveling direction, the attachment portion being detachably attached to an attachment-receiving portion comprising a contact surface, and the attachment portion having a surface facing a direction different from a direction of the first surface and bonded to the sheet member,
• wherein the attachment-receiving portion is provided on a portion of an outer peripheral surface of the cylinder body which is located on the upstream side of the recessed portion in the rotation direction, and
• the attachment portion is attached to the attachment-receiving portion in a state where the attachment portion is disposed outside the attachment-receiving portion in a radial direction.
