Summary:PROBLEM TO BE SOLVED: To provide a fixing device that can reduce wear of a heating layer of a film to reduce uneven heating of the film.SOLUTION: In the longitudinal direction orthogonal to a conveying direction of a recording material P, conductive layers 4A and 4B are provided on the outer peripheral surfaces of both ends of a heating layer 12 of a film 1 across the circumferential direction of the heating layer; a slide member 2 sliding on an inner peripheral surface of the heating layer has both ends 2A and 2B that overlap with the conductive layers; both ends of the slide member are arranged on the outsides of inner end faces 4Ai and 4Bi of the conductive layers.SELECTED DRAWING: Figure 3 【課題】フィルムの発熱層の摩耗を軽減してフィルムの発熱ムラを抑制可能な定着装置を提供すること。【解決手段】記録材Ｐの搬送方向に直交する長手方向において、フィルム１の発熱層１２の両端部の外周面には前記発熱層の周方向に亘って導電層４Ａ，４Ｂが設けられ、前記発熱層の内周面に摺動する摺動部材２は前記導電層とオーバーラップする両端部２Ａ，２Ｂを有し、前記摺動部材の両端部は前記導電層の内側端面４Ａｉ，４Ｂｉよりも外側に配置されている。【選択図】図３
