Abstract
An image forming apparatus includes an image bearing member for bearing an image, a rotatable recording material bearing member for bearing a recording material and conveying the recording material to a transfer station, the image formed on the image bearing member being transferred onto the recording material born on the recording material bearing member at the transfer station, and a cleaning means capable of being contacted with a surface of the recording material bearing member to clean the surface of the recording material bearing member at a cleaning station. When a length (L1) of a recording material born on the recording material bearing member in a rotational direction of the recording material bearing member is greater than a distance (L2) from the transfer station to the cleaning station along the rotational direction of the recording material bearing member, after the image is transferred onto the recording material born on the recording material bearing member, the recording material is conveyed to the transfer station again.
