ABSTRACT:
An image forming apparatus comprising an image forming unit for forming a non-fixed toner image on a recording material, a heater for heating the non-fixed toner image, a back-up member for cooperating with the heater to form a nip therebetween, the back-up member pinching and conveying the recording material at the nip in such a manner that the non-fixed toner image is contacted with the heater so that the non-fixed toner image is fixed to the recording material by heat from the heater, and a cleaning member for cleaning the back-up member. The cleaning member is brought into a first and second cleaning mode in which an image forming operation is not effected and the back-up member is cleaned, the second cleaning mode having a cleaning time longer than a cleaning time of the first cleaning mode.
