Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus where heating by a heater of a fixing unit is surely stopped in the case of detecting the abnormal temperature of the fixing unit.  <P>SOLUTION: The temperature of a fixing part 3 is detected by a temperature sensor 32, and is led to a controlling part 4. The controlling part 4 outputs on/off signals to a switch 5 so that the detected temperature by the temperature sensor 32 can be kept in a first level, and the supply of electric power to the heater 31 (fixing part 3) is controlled. On the other hand, when the controlling part 4 does not function due to any abnormality and the detected temperature exceeds the first level and rises to a second level, a high temperature detection circuit 6 is actuated, so that a switch 2 in a turn-on state is forcedly switched to a turn-off side. Thus, the supply of the electric power to the heater 31 is stopped. Since the switch 2 for supplying the electric power keeps a turn-off state even though the detected temperature by the temperature sensor 32 drops, the supply of the electric power to the heater 31 is not restarted even though the controlling part 4 is actuated.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
