Patent ID: 8811875

Claim:
A fixing device comprising: an endless fixing belt that is put in contact with a toner image on a fixed medium and fixes the toner image to the fixed medium; a heat roller for heating the fixing belt; a fixing roller that suspends the endless fixing belt between the heat roller and itself and has a silicone rubber layer that comes into pressing contact with the toner image on the fixed medium via the fixing belt; a pressing roller that presses the fixing roller via the fixing belt; and a meander regulating member that presses the fixing belt against the fixing roller from the paper input side, at the side end of the fixing belt on the side to which the fixing belt is moved off with respect to the longitudinal direction of the fixing roller, wherein the fixing belt is configured to receive a rotational force only through a nip portion of the pressing roller, wherein the meander regulating member is disposed at either end of the fixing roller with respect to the longitudinal direction, so that at least one of the side ends of the fixing belt abut the meander regulating member, and wherein the meander regulating member is a rotatable roller having a counter-tapered shape that becomes wider as it goes to either axial end.
