A fixing device (15) includes a temperature controller (54) that controls a temperature of a fixing rotary body (46) to heat the fixing rotary body (46) to a plurality of preset target temperatures that includes a first target standby temperature (T0), a target fixing temperature (T1), a target idle temperature (T2), and a second target standby temperature (T3, T4). When the target fixing temperature (T1) is lower than the first target standby temperature (T0), the temperature controller (54) separates a pressing rotary body (1) from the fixing rotary body (46) to idle the fixing rotary body (46) for a predetermined idle time period (P1) before a fixing operation starts. After the fixing operation, the temperature controller (54) controls a heater (52) to change the temperature of the fixing rotary body (46) to the second target standby temperature (T3, T4). |
