ABSTRACT:
An image forming apparatus equipped with a heat fixing device includes a heating member having an elastic layer on a substrate and a fluorine resin coated on the elastic layer, a pressure member having a substrate covered with a fluorine resin tube through an elastic layer or without the elastic layer in pressure contact with the heating member, and at least one heater as a heat source. The surface roughness of the fluorine resin of the heating member is greater than the surface roughness of the fluorine resin tube of the pressure member.
