Abstract A fixing device (20; 20S) includes a fixing rotary body (21) and an opposed body (22) contacting the fixing rotary body (21) to form a fixing nip (N) therebetween through which a recording medium is conveyed. A heat shield (27; 27S) is interposed between the heater (23) and the fixing rotary body (21) to shield the fixing rotary body (21) from the heater (23). A driver (46) drives and moves the heat shield (27; 27S) between a shield position where the heat shield (27; 27S) is interposed between the heater (23) and the fixing rotary body (21) to shield the fixing rotary body (21) from the heater (23) and a retracted position where the heat shield (27; 27S) is retracted from the shield position. A reinforcement (53; 53S; 53T; 53U) is mounted on a long edge of the heat shield (27; 27S).
