Disclosed is an image forming apparatus in which an increase in the service life is compatible with a reduction in apparatus size and cost and which provides high productivity in image formation. The image forming apparatus includes: an image bearing member; an image forming unit; an intermediate transfer device; a final transfer member; a potential gradient forming unit; and a cleaning unit; an upstream side cleaning roll,a downstream side cleaning roll which is in contact with the intermediate transfer member on the downstream side of the upstream side cleaning roll with respect to a feedback direction in which the residual toner is fed back from the final transfer position to the primary transfer position, and a cleaning brush which is in contact with the intermediate transfer member on the downstream side of the upstream side cleaning roll and on the upstream side of the downstream side cleaning roll. |
