Description
上記目的を達成するために、本発明の画像形成装置は、定着部材と加圧ローラとを用いてシートのトナー画像を加熱定着する画像形成装置であって、第１の電源と、前記第１の電源よりも高い電圧の第２の電源と、オン／オフ操作により前記第１の電源及び前記第２の電源をオン／オフする電源スイッチと、前記電源スイッチのオン／オフ操作を検出する検出手段と、前記定着部材と前記加圧ローラとを接近離間動作させる駆動手段と、前記検出手段により前記電源スイッチのオフ操作が検出された場合に、前記第２の電源をオフさせた後に前記第１の電源をオフさせてシャットダウン処理を行う電源制御手段と、前記電源制御手段により前記第２の電源をオフさせた後に前記第１の電源をオフさせるまでの時間内に前記第１の電源により前記駆動手段を駆動して前記定着部材と前記加圧ローラとを離間動作させる駆動制御手段と、を備えることを特徴とする。 In order to achieve the above object, an image forming apparatus of the present invention is an image forming apparatus that heats and fixes a toner image on a sheet using a fixing member and a pressure roller, and includes a first power source and the first power source. A second power source having a voltage higher than that of the power source, a power switch for turning on / off the first power source and the second power source by an on / off operation, and detection for detecting an on / off operation of the power switch And a driving means for moving the fixing member and the pressure roller closer to and away from each other, and when the detection means detects an off operation of the power switch, the second power is turned off and the second power is turned off. Power supply control means for performing a shutdown process by turning off the power supply of the first power supply, and by the first power supply within a time period after the second power supply is turned off by the power supply control means and before the first power supply is turned off. in front By driving the driving means, characterized in that it comprises a drive control means for separating operation of said pressure roller and said fixing member.
