ABSTRACT:
A fixing device comprises a heat fixing roller in which a heat resistant elastic layer is formed on a cylindrical metal core and, further, a heat resistant resin layer is coated on the surface thereof, an endless belt, a pressure member disposed in the inside of the endless belt, wherein the endless belt is wound around the heat fixing roller for a predetermined angle to form a nip area between the endless belt and the heat fixing roller for allowing a recording sheet to pass therethrough, the pressure member is pressed by way of the endless belt to the heat fixing roller at the nip area thereby forming distortion in the heat resistant elastic layer of the heat fixing roller. An image forming apparatus using the fixing device can satisfy improved image quality, extended working life, energy saving and high speed operation altogether.
