ABSTRACT:
An image forming apparatus, is provided with a fixing device including a heat source to receive power supply and to generate heat, and a temperature sensor to detect a temperature of the heat source; a control section to conduct a heat source temperature control and an abnormal temperature detecting control in response to a detection result of the temperature sensor; and an electric power cutout section to cut out the power supply to the heat source on a basis of the abnormal temperature detecting control by the control section. The control section conducts the heat source temperature control for the fixing device and/or the abnormal temperature detecting control for the electric power cutout section with at least two CPUs.
