Abstract
An image forming apparatus includes a rotatable image carrying member, a rotatable transfer member cooperative with the image carrying member, and a fixing unit having a fixing nip for nipping and feeding the recording material discharged from the transfer nip while fixing the toner image. In addition, a bowing amount measuring unit measures a bowing amount of the recording material, a storing portion stores a target bowing amount, and a speed controller controls a feeding speed of the recording material. The storing portion stores a plurality of target bowing amounts, which are selectable depending on kinds of the recording material, and the speed controller controls the feeding speed in the fixing nip, and then controls the feeding speed so that the bowing amount is substantially zero at the time when a trailing edge of the recording material leaves the transfer nip.
