PROBLEM TO BE SOLVED: To provide a fixing device by which paper is orderly stacked on an ejected paper tray by uniformizing the feeding property of the paper in a width direction by uniformizing pressure distribution in a nip and by obediently feeding the paper to a feeding path without causing extreme downward curling. SOLUTION: In the fixing device constituted of a heater base plate on which a heating element is formed of the alloy of silver-palladium or the like on a ceramic base plate or the base plate of stainless steel or the like and also it is coated with a glass layer, a member (a base plate supporting member) to support the heater base plate, a member made of metal provided so as to reinforce the member and to apply pressure, film made of plastic to incorporate them and a rubber roller rotated and driven by abutting on the film, the curvature of a rubbing surface between the base plate supporting member and a film inner surface is set lower than that of a pressure roller on a downstream side in a pressure area.
