<P>PROBLEM TO BE SOLVED: To provide, with a simple configuration, a fixing device that can suppress wrinkling of paper while maintaining a prescribed nip pressure and can suppress wear of a fixing member by maintaining the fixed axial distortion of the fixing member in a fixing nip area in the conveying direction of the fixing member, and to provide an image forming apparatus having the same. Ž<P>SOLUTION: The fixing device has a pressing member 305 that firmly presses the fixing belt 303 against a heat roll 301 from the rear side of the fixing belt 303. The nip pressures of both the axial ends of the fixing nip area N are set higher than the nip pressure in the axial center of the area. In addition, the shape of the pressing member 305 is set so that a distance between the rear side of the fixing belt 303 and the pressing face 305S of the pressing member 305 on the upstream side of the fixing nip area N may gradually increase from the axial center Rc toward both the ends Re, thereby fixing the distortion of the fixing members 301 and 303 on the upstream side of the fixing nip area N in the axial direction of the conveying member.
