ABSTRACT:
An image forming apparatus is disclosed which interrupts the power supply to the sensors that are used during image formation when it is impossible to form an image, thereby allowing the image forming apparatus so save energy more effectively. The image forming apparatus controls the power supply to sensors that are used during image formation, other than a heating temperature sensor and fixation control sensors, such that the image forming apparatus interrupts the power supply when switched to the non-fixation operation control state, and supplies power when switched to the fixation operation control state and the temperature detected by the heating temperature sensor is equal to or greater than a predetermined temperature near the fixation temperature.
