Description
本発明の画像形成装置は、ヒータの発熱により画像を記録材に定着させる定着器と、前記定着器の外部から印加される直流電圧を、前記定着器の内部を介して前記定着器の外部に返すループバック部を有し、前記定着器が取り外された状態では、前記ループバック部が前記直流電圧を前記定着器の外部に返せないよう構成されるコネクタと、前記ヒータへの電力の供給経路に設けられ、前記ループバック部を通過した前記直流電圧により動作し、開閉することで前記電力の前記ヒータへの供給を制御する開閉手段と、前記定着器が前記コネクタを介して接続され、前記開閉手段の開閉を制御して前記ヒータの温度を制御する制御手段と、を備え、前記開閉手段は、前記コネクタに接続異常が発生したときに、前記直流電圧が印加されなくなることで開状態になり、前記電力の前記ヒータへの供給を遮断することを特徴とする。 The image forming apparatus of the present invention has a fuser that fixes an image on a recording material by heat generation of a heater , and a DC voltage applied from the outside of the fuser to the outside of the fuser via the inside of the fuser. A connector having a loopback portion for returning, and in a state where the fuser is removed, the loopback portion is configured so that the DC voltage cannot be returned to the outside of the fuser, and a power supply path to the heater. The fuser is connected to the opening / closing means which controls the supply of the electric power to the heater by opening / closing by operating by the DC voltage passing through the loopback portion, and the fuser is connected via the connector. The opening / closing means is provided with a control means for controlling the opening / closing of the opening / closing means to control the temperature of the heater, and the opening / closing means is opened by not applying the DC voltage when a connection abnormality occurs in the connector. Therefore, the supply of the electric power to the heater is cut off.
