description To provide an image forming apparatus that can prevent an increase in temperature of a static eliminating member that eliminates static electricity on a fixing member.SOLUTION: An image forming apparatus comprises: a fixing member 22 that is in contact with a sheet to which a toner image is transferred to fix the toner image to the sheet; bearing parts 25 that are electrically grounded and provided in contact with the fixing member 22; a heater 23 that is provided inside the fixing member 22 and heats the fixing member 22 according to power supply; and a coil spring 43 that is provided on an energization path between the bearing part 25 and the ground and is fused when a current exceeding a predetermined threshold flows.SELECTED DRAWING: Figure 2 【課題】定着部材を除電する除電部材の高温化を抑制可能な画像形成装置を提供すること。【解決手段】画像形成装置は、トナー像が転写されたシートと接触して前記トナー像を前記シートに定着させる定着部材２２と、電気的に接地されており、定着部材２２に接触して設けられる軸受け部２５と、定着部材２２の内部に設けられ、給電に応じて定着部材２２を加熱するヒーター２３と、軸受け部２５とアースとの間の通電経路に設けられ、予め定められた閾値を超える電流が流れた場合に溶断するコイルバネ４３と、を備える。【選択図】図２
