Abstract
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 to form a fixing nip therebetween through which a recording medium is conveyed. A heat shield is movable in a circumferential direction of the fixing rotary body and interposed between the heater and the fixing rotary body to shield the fixing rotary body from the heater. A driver is connected to the heat shield to drive and move the heat shield between a shield position where the heat shield is interposed between the heater and the fixing rotary body to shield the fixing rotary body from the heater and a retracted position where the heat shield is retracted from the shield position. A reinforcement is mounted on a long edge of the heat shield.
