Summary:PROBLEM TO BE SOLVED: To inhibit the occurrence of heat-generation unevenness of a belt in its rotational direction caused by the fact that a conductive layer is shaved due to wear due to slide between a power supply part and the conductive layer, when a belt heating system fixing device using the belt generating heat by the supply of power is used for a long period of time, in the belt heating system fixing device.SOLUTION: A power supply member is provided on an outer circumferential surface side or an inner circumferential surface side of a heat generation layer of the belt and the conductive layer is provided on the side of a surface opposite to the surface on which the power supply member is provided, of the heat generation layer in the rotational direction of the belt. 【課題】 給電によって発熱するベルトを用いたベルト発熱方式の定着装置において、定着装置を長期間使用すると、給電部と導電層の摺動による摩耗によって導電層が削れてベルトの回転方向の発熱むらが発生する。【解決手段】 ベルトの発熱層の外周面側又は内周面側のいずれか一方に給電部材を設け、発熱層の給電部材が設けられた面と反対の面の側にベルト回転方向に亘って導電層を設ける。【選択図】 図１
