Abstract
A fixing apparatus includes: a cylindrical heat roller having a heating resistor layer on an inside surface thereof; a pressure member in pressure contact with the cylindrical heat roller; and a pair of electrodes provided in the cylindrical heat roller for supplying electricity to the heating resistor layer so that the heating resistor layer generates heat. Both ends of the cylindrical heat roller are formed so as to restrain radiating heat in the cylindrical heat roller from openings at the both ends of the cylindrical heat roller.
