Abstract
A fixation unit which allows paper with a toner image formed thereon to be fed between a first roller and a second roller for fixing the toner image on the sheet. The fixation unit includes a drive controller. The drive controller rotates the first and second rollers on different driving conditions. The drive controller rotates the first roller at a constant circumferential speed at least in a state where the first and second rollers are in pressure contact with each other and rotates the second roller with a constant torque which is low enough for the second roller to stop rotating when the first roller stops rotating.
