Abstract
An image forming apparatus may include a transfer nip, a first conveyance belt, a second conveyance belt, a fixing nip, a fixing drive unit, and a control unit. The first conveyance belt conveys the sheet to which a toner image is transferred and fixed. The fixing drive unit drives the fixing nip so that the fixing nip conveys the sheet at a speed that is higher than the transfer speed in a high speed fixing mode in which the fixing nip fixes the toner image to the sheet while conveying the sheet. The control unit sets a circumferential speed of the first conveyance belt and a circumferential speed of the second conveyance belt so that the sheet bridging the first and second conveyance belts is pulled by the second conveyance belt to slide on the first conveyance belt in the high speed fixing mode.
