Disclosed is an image forming apparatus capable of preventing generation of an excessive difference in potential between a cleaning member and an intermediate transfer member to thereby increase the service life of the intermediate transfer member. The image forming apparatus includes: an image bearing member; an image forming unit which 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 which applies an intermediate-transfer-member-bias to the intermediate transfer member and applies a cleaning-member-bias to the cleaning member which is in contact with the intermediate transfer member to thereby control the potential gradient between the cleaning member and the intermediate transfer member.
