| description | To prevent the occurrence of electrostatic offset with a configuration in which dielectric breakdown is less likely to occur.SOLUTION: A fixing device has: a film; a nip part forming unit that has a heater (22); and a pressure member. The heater (22) has a metal substrate (22a), an insulating layer (22b) that is formed on the substrate, and heating elements (22c) that are arranged on the insulating layer and generate heat upon energization. The fixing device further has voltage application means (DC1) that applies a voltage having the same polarity as the normal electrification polarity of toner to the substrate (22a).SELECTED DRAWING: Figure 6
【課題】絶縁破壊が生じにくい構成で静電オフセットの発生を抑制する。【解決手段】定着装置は、フィルムと、ヒータ（２２）を有するニップ部形成ユニットと、加圧部材と、を有する。ヒータ（２２）は、金属製の基板（２２ａ）と、基板上に形成された絶縁層（２２ｂ）と、絶縁層上に配置され、通電されることで発熱する発熱体（２２ｃ）と、を有する。定着装置は、トナーの正規帯電極性と同極性の電圧を基板（２２ａ）に印加する電圧印加手段（ＤＣ１）をさらに有する。【選択図】図６ |
