摘要：
A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation and a heater disposed opposite and heating the fixing rotary body. An opposed body contacts the fixing rotary body with releasable pressure therebetween to form a fixing nip therebetween through which a recording medium is conveyed. A heat shield is interposed between the heater and the fixing rotary body and movable in a circumferential direction of the fixing rotary body between a home position where the heat shield is disposed opposite the heater indirectly and a shield position where the heat shield is disposed opposite the heater directly to shield the fixing rotary body from the heater. A controller is operatively connected to the heat shield to move the heat shield to the home position when a print job is finished.
