Claims (1)
- 用紙上に形成されたトナー像を加熱定着する定着ローラを目標温度に加熱制御する加熱制御手段と、給紙される用紙の種類とサイズを選択する用紙選択手段と、複写動作の実行中に前記用紙選択手段により選択された用紙が標準用紙であれば前記目標温度を標準温度に切り替え、標準用紙よりも厚さが厚い厚紙であれば前記目標温度を前記標準温度よりも高い温度に切り替える定着温度切替手段と、給紙される用紙のサイズを検出するサイズ検出手段とを備えて構成される画像形成装置であって、
前記定着温度切替手段は、前記目標温度を前記標準温度よりも高い温度に切り替えた状態で、前記サイズ検出手段により検出されたサイズが前記用紙選択手段により選択されたサイズと異なるときに、前記目標温度を前記標準温度よりも高い温度から前記標準温度に再切替するように構成されている画像形成装置。
