Summary:To solve the problem in which: in an image forming apparatus including a fixing unit that can exclusively switch a plurality of heating elements having different longitudinal lengths, the switching of the heating elements extends warm-up time of a fixing unit.SOLUTION: An image forming apparatus switches a power supply line such that a heating element having a longest longitudinal length can be supplied with power after completion of fixing processing, and subsequently completes an image forming job.SELECTED DRAWING: Figure 7 【課題】 長手長さが異なる複数の発熱体を排他的に切り替え可能に構成された定着部を備える画像形成装置において、発熱体の切り替えによって定着部のウォームアップ時間が長くなる。【解決手段】 定着処理を終えた後に長手長さが最も長い発熱体に電力供給可能になるように電力供給ラインを切り替えてから画像形成ジョブを終了する。【選択図】 図７
