An image forming apparatus has a heating rotator 12 that is heated by a first heat source 18 , a pressurizing rotator 24 that is heated by a second heat source 28 , that is in pressure contact with the heating rotator 12 , and that forms a fixing nip 26 between the pressurizing rotator 24 and the heating rotator 12 , a temperature sensor St that detects a temperature in the apparatus, and a controller 124 that controls temperatures of the heating rotator 12 and of the pressurizing rotator 24 by on-off control over the first heat source 18 and the second heat source 28 , respectively, and that sets the temperature of the pressurizing rotator 24 higher than a normal temperature on condition that the temperature detected by the temperature sensor St exceeds a specified value. |
