摘要： Deflection recessed in a bow shape at the axial central portion in the longitudinal direction of the transfer member is avoided to prevent failure in image caused by the transfer nip being improperly forming at the central portion. The pressing force of the transfer member against an image bearing member resulting in failure in transfer is made uniform in the longitudinal direction. The transfer member forming the transfer nip are pressed toward the photosensitive drum at the central portion in the longitudinal direction or in the positions which are spaced apart toward the center from the ends to avoid the deflection of the transfer member.

摘要： 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.
