Abstract
An image forming apparatus includes an image bearing member for bearing a toner image; a rotatable intermediary transfer member; and a transfer unit, configured and positioned to form a transfer nip between the intermediary transfer member and the image bearing member, for transferring the toner image from the image bearing member onto a surface of the intermediary transfer member. The transfer unit includes a sheet member on which the intermediary transfer member is slidable, and includes an elastic member for urging the sheet member toward the intermediary transfer member at a position of the transfer nip. The sheet member is provided with a reinforcing portion, having a linear expansion coefficient different from that of the sheet member, in an area in which the elastic member urges the sheet member.
