Abstract
In a fixing device in which fixing defects can be suppressed and which can be reduced in size, and an image forming apparatus comprising the fixing device, setting is performed such that the surface temperature of an outer peripheral belt surface serving as a non-heated belt surface of a fixing belt is substantially equal at a heating region inlet at the upstream end of a heating region and a heating region outlet at the downstream end of the heating region such that the temperature difference between the surface temperature of the outer peripheral belt surface at the heating region inlet and the surface temperature of the outer peripheral belt surface at the heating region outlet is no more than 5 [° C.].
