ABSTRACT:
The invention provides an image forming apparatus including an image bearing member, an intermediate transferring member for receiving a transfer of a toner image from the image bearing member, a cleaning unit which cleans the toner image on the intermediate transferring member, a first mode for transferring a toner image on the intermediate transferring member onto a transfer material, and a second mode for cleaning the toner image without transfer to the transfer material. It is thus possible to prevent image failures resulting when the intermediate transferring member is started to be used from a new state or when the image forming apparatus is started to be used after a prolonged pause.
