Abstract
A fuser apparatus including: a fuser member having an endless contact surface to be brought into contact with each of successively transported recording media and a non-contact surface and being arranged to apply heat to the recording medium from the contact surface to fix a toner on the recording medium; a heating member energized to supply heat to the contact surface; a contact surface temperature detecting member for detecting a temperature of the contact surface; a non-contact surface temperature detecting member for detecting a temperature of the non-contact surface; and an energization controlling member for controling energization power of the heating member; wherein the energization controlling member controls the heating member energization power so that the heating member energization power is reduced as a difference between the non-contact surface temperature and the contact surface temperature decreases.
