Abstract
The present invention provides an image forming apparatus comprising an image bearing member, and a recording material bearing member for bearing a recording material to convey the recording material to a transfer station where an image is transferred from the image bearing member onto the recording material borne on the recording material bearing member. The recording material bearing member is capable of bearing a plurality of recording materials simultaneously at different positions thereon. The images can be successively transferred onto first and second surfaces of each recording material, and, when images are formed on the second surfaces of the plurality of recording materials, during a time period in which an area of the recording material bearing member with which the first surface of the recording material was previously contacted is passing through at least the transfer position without bearing the recording material, a spacer particle layer is formed between the image bearing member and the area.
