PROBLEM TO BE SOLVED: To ensure satisfactory fixability, even while ensuring on-demand performance of a heat fixing device of a belt heating system. SOLUTION: The heat fixing device is configured such that a heat-resistant endless belt is slid and conveyed while kept in close contact with a heating element by means of a pressing member, a material to be heated is introduced between the belt and pressing member forming a pressure contact nip, and the pressure contact nip is sandwiched and conveyed together with the belt, thereby applying the heat of the heating element to the material. In the heat fixing device, the average value of the pressure on the rear half of the pressure contact nip is higher than that on the front half thereof. COPYRIGHT: (C)2011,JPO&INPIT
