ABSTRACT:
A belt-type fixing device is provided in which a wide fixing nip having a generally flat pressure distribution with respect to a paper feeding direction can be formed.The belt-type fixing device of the invention has a nip forming member that is fixed inside an endless-sheet-like fixing belt to be heated so as to be incapable of rotating, and a rotatable pressurizing roller that is in pressure contact with the nip forming member with the fixing belt interposed between. Contact part between the fixing belt and the pressurizing roller forms a fixing nip, and a surface of the nip forming member that is opposite to the pressurizing roller is configured as a curved surface extending along an outer circumferential surface of the pressurizing roller so that a pressure distribution in the fixing nip is made generally flat with respect to the paper feeding direction.
