Abstract
A fixing device includes a fixing pad and a heater. The fixing pad is in contact with an inner surface of a fixing belt and is located opposite a pressure roller to form a nip between the fixture and the pressure applicator where the pressure is applied to the paper. The heater is attached to the fixing pad and has a positive temperature coefficient. The heater has a heating surface that faces toward the nip and generates heat. The heating surface and the inner surface of the fixing belt have an insulating layer (substrate) therebetween.
