Summary:PROBLEM TO BE SOLVED: To provide a technology that can suppress unevenness in temperature in a fixing device including a heating element as part of a layer of a rotor.SOLUTION: In a fixing device comprising a rotor 36 that includes a heating element 36b and a pressure body that is in pressure contact with the rotor 36 to form a fixing nip part, the rotor 36 includes a conductive layer 36a formed with the heating element 36b as an outer layer; the heating element 36b includes a cylindrical part that is formed on the conductive layer 36a to continue over the entire periphery in the direction of rotation of the rotor 36 and fed with power from a power feeding member, and divided parts that are formed on the conductive layer 36a at intervals in the rotation direction.SELECTED DRAWING: Figure 3 【課題】回転体の層の一部として発熱体を備える定着装置において温度ムラの抑制を図ることができる技術を提供する。【解決手段】発熱体36bを有する回転体36と、回転体36に圧接して定着ニップ部を形成する加圧体と、を備える定着装置において、回転体36は、発熱体36bが外層として形成される導電層36aを有し、発熱体36bは、導電層36a上において回転体36の回転方向に全周にわたって連続するように形成され、給電部材から給電を受ける筒状部と、導電層36a上において回転方向に間隔を空けて形成される分割部と、を有する。【選択図】図3
