ABSTRACT:
A fixing device fixes an image on a recording medium by allowing the recording medium to pass through a nip between a pair of rotating members at least one of which is heated. The fixing device includes heaters that heat rotating members, temperature sensing elements that sense the temperature of the rotating members, and an I/O control panel. The I/O control panel calculates the amount of heat generated by the heaters based on the temperature sensed by the temperature sensing elements, and corrects calculation result according to medium information to control the heaters.
