摘要： In one embodiment, a fixing apparatus is configured of a pressing portion for causing the pressure roller to enter a pressure applied state by applying bias, a switching portion for causing the pressing portion in the pressure applied state to enter a pressure released state by causing a cam to rotate forward, a pressure state detection portion for detecting the pressure released state, and a control portion for, when shifting from the pressure applied state to the pressure released state, turning forward the cam of the switching portion in the pressure applied state and stopping the cam after the pressure state detection portion detects the pressure released state. If the cam is turned forward with respect to the switching portion for a certain time period, but the pressure state detection portion does not detect the pressure released state, the control portion performs forward rotational direction retry control.

摘要： In one embodiment of the present invention, a fixing apparatus that causes a recording material to pass through a nip portion formed by a rotating heat roller and a rotating pressure roller being in contact so as to perform a fixing operation is configured including a pressing mechanism that can switch between a pressure applied state in which the pressure roller presses against the heat roller using a bias and a pressure cancelled state in which the pressure is cancelled, a pressure state detection unit, and a control unit that performs a pressure cancelation operation and a pressure application operation. If the pressure state detection unit does not detect the pressure cancelled state even when the control unit has performed pressure cancellation control for a certain time period with respect to the pressing mechanism in the pressure applied state, the control unit permits a fixing operation in only the pressure applied state after performing pressure application control for a certain time period with respect to the pressing mechanism.
