PROBLEM TO BE SOLVED: To provide an image forming device capable of reporting a failure or the like when a power is applied, and preventing a fixing device from excessive elevation of temp. SOLUTION: This device is provided with a judging means 130 judging whether the temp. according to a detecting signal of a thermistor 114 is lower than a specified temp. or not, inside a controlling device 120, and equipped with a failure detecting means capable of working at the time the judging means 130 judges that the temp. according to the detecting signal of temp. detecting means is lower than the specified temp. when the power is applied, on the controlling means 120. The failure detecting lets the power source feed power to a heater 150 for a specified time, a specified time after the turning on of the power source, and when receiving such as signal that the temp. according to the detecting signal of the thermistor 114 from the judging means 130 is lower than a specified temperature within the time the power is being applied on the heater 150, informs of the failure. |
