ABSTRACT:
An image forming apparatus has a heating rotator12that is heated by a first heat source18, a pressurizing rotator24that is heated by a second heat source28, that is in pressure contact with the heating rotator12, and that forms a fixing nip26between the pressurizing rotator24and the heating rotator12, a temperature sensor St that detects a temperature in the apparatus, and a controller124that controls temperatures of the heating rotator12and of the pressurizing rotator24by on-off control over the first heat source18and the second heat source28, respectively, and that sets the temperature of the pressurizing rotator24higher than a normal temperature on condition that the temperature detected by the temperature sensor St exceeds a specified value.
