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.
