Abstract
Disclosed is an image forming apparatus which is compact and inexpensive, and which allows cleaning of a final transfer member. The image forming apparatus includes: an image bearing member; an image forming unit that forms a toner image on the surface of the image bearing member; an intermediate transfer device formed by at least one intermediate transfer member, and which is in contact with the image bearing member; a final transfer member which is in contact with the intermediate transfer member; a cleaning member which is in contact with the intermediate transfer member; and a control unit that controls the potential gradient between the image bearing member, the intermediate transfer member, the final transfer member, and the cleaning member, in which the control unit forms in an image formation mode a potential gradient for image formation which causes reverse-polarity toner on the final transfer member to adhere to the cleaning member by way of the intermediate transfer member.
