16/10 A TONER IMAGE PRESSURE-FIXING DEVICE ABSTRACT OF THE DISCLSOURE A toner image pressure-fixing device has a pair of pinch rolls arranged in rolling engagement with each other to provide a nip through which a carrier sheet with a deposit of toner particles thereon is passed to fix the deposit to the carrier sheet by pressure. One of the pinch rolls is of a diameter smaller than that of the other and is solid while the other pinch roll is hollow. The small- diameter pinch roll is resiliently urged against the large-diameter pinch roll by leaf springs and is backed up by a single back-up roll which is disposed on the side of the small-diameter pinch roll sub- stantially diametrically opposite to the large- diameter pinch roll and is resiliently urged against the small-diameter pinch roll whereby the small- diameter pinch roll is prevented from being deflected by pressure produced when a carrier sheet is passed through the nip between the pinch rolls.
