Abstract: Disclosed herein are an image fixing device and an image forming apparatus having the same. The image fixing device includes a fixing belt which is rotatably disposed, and a pressure roller which is disposed to be opposite to the fixing belt and thus to press an outer circumferential surface of the fixing belt, wherein the fixing belt includes a fixing part of which an outer surface has a first friction coefficient, and a meandering movement preventing part which is located at each of both ends of the fixing part in a length direction of the fixing belt, and of which an outer surface has a second friction coefficient greater than the first friction coefficient. By the configuration, a meandering movement of the fixing belt is prevented, and thus it is possible to improve fixing efficiency.
