Summary:PROBLEM TO BE SOLVED: To provide a heater which can excellently suppress breakage of a rotational member with a heat generation layer.SOLUTION: The heater includes: a heating rotational member 1 having a heat generation layer 13, the heat generation layer generating heat by electric conduction; electricity supply members 5a and 5b which form electricity-supplied regions F1 and F2 by getting in contact with the heat generation layer; and a pressurizing rotational member 3 which forms nip regions N1 and N2 by getting in contact with the heating rotational member, the nip regions heating an image T supported by a recording material P and the electricity-supplied regions being located on the inner side of the nip regions alone.SELECTED DRAWING: Figure 3 【課題】発熱層を有する回転部材の破損の抑制に優れる加熱装置を提供すること。【解決手段】通電によって発熱する発熱層１３を有する加熱回転部材１と、前記発熱層と接触して給電領域Ｆ１，Ｆ２を形成する給電部材５ａ，５ｂと、前記加熱回転部材と接触してニップ領域Ｎ１，Ｎ２を形成する加圧回転部材３と、を有し、前記ニップ領域で記録材Ｐが担持する画像Ｔを加熱する加熱装置において、前記給電領域は前記ニップ領域の内側のみに配置することを特徴とする。【選択図】図３
