Abstract
An image forming apparatus includes a paper feed unit, an image forming unit, a fixing unit, a conveyance unit, a control unit, a movement unit and an actuator. The fixing unit includes sandwiching members between which paper is sandwiched. The paper has a toner image thereon formed by the image forming unit. The sandwiching members form a nip part, and the fixing unit fixes the toner image to the paper at the nip part. When an execution condition is satisfied, the control unit performs first control under which the actuator releases a sandwiching pressure made by the sandwiching members and thereafter the movement unit moves the sandwiching members along a paper width direction which is at right angles to a conveyance direction of the paper.
