Patent ID: 7349659

Claim:
An image forming apparatus, comprising: an image forming section which transfers toner onto a latent image due to a difference of electrostatic potential to form a toner image; a transfer section which transfers the toner image onto a recording material directly or via an intermediate transfer body; a fixing section which has a pair of rotatable members contacted and pressed each other, in which the recording material on which the toner image is transferred is passed through the pair of rotatable members, and heats and presses the toner image to fix the toner image on the recording material; a cleaning section which cleans a peripheral surface of one of the pair of rotatable members of the fixing section; a paper dust amount measuring section which measures an amount of paper dust separably adhering to the recording material, before the toner image is transferred; and a control section which controls a cleaning operation rate of the cleaning section based on the amount of paper dust measured by the paper dust amount measuring section.
