Abstract
An image forming apparatus includes an image bearing member that carries a toner image, a rotatable endless belt facing the image bearing member, and a transfer device arranged on an inner peripheral side of the belt and transferring a toner image from the image bearing member to the belt. The transfer device includes a sheet member having conductivity and having a free end and an opposite end which is fixed. In addition, a support member supports and contacts the sheet member, and a securing member secures the sheet member. The sheet member at least has a first region secured by the securing member, a second region in contact with the support member, a third region separated from the support member and the belt, and a fourth region separated from the support member and in contact with the belt. The first region, the second region, the third region and the fourth region are located in order from an upstream side toward a downstream side in a rotational direction of the belt.
