Abstract: A heating roller assembly for an image forming apparatus. The heating roller assembly includes a heating roller pipe having a heating layer around which a coil is wound. The heating layer has a coil winding structure such that first portions ‘A’ formed adjacent to bearings for rotatably supporting the heat roller pipe have a lower thermal temperature than that of second portions ‘B’ formed adjacent to the first portions A. The first portions A serve as a heat absorber to minimize the fusing heat loss at the beginning of a fusing process, and even if the fusing process continues for a long time, the heat absorber can prevent the opposite ends of the heating roller, where the bearings are disposed, from overheating. Accordingly, a more accurate pickup operation is achieved and a stable quality of image can be guaranteed.
