Abstract
A belt-type fixing device is provided in which a nip pressure distribution in a fixing nip is made generally uniform with respect to a paper feeding direction and which thereby prevents occurrence of image noise even when a thick paper is fed. The belt-type fixing device has: an endless-sheet-like fixing belt, a pressurizing roller which has elasticity and on which a paper is passed through a fixing nip that is contact part between the pressurizing roller and an outer circumferential surface of the belt member, and a nip forming member which is provided in contact with an inner surface of the fixing belt, which relatively presses the fixing belt against the pressurizing roller, of which an opposite surface pressing the pressurizing roller is formed as a curved surface extending along an outer circumferential surface of the pressurizing roller, and of which the opposite surface is composed of an elastic layer.
