摘要： In one embodiment, when a hot roller is driven to rotate, a driving gear rotates so that a swing gear and a swing cam rotate. Then, a sliding contact edge on the right side of a swing lever that abuts against the circumferential face of the swing cam repeatedly moves up and down, and the swing lever repeatedly rotates clockwise and counterclockwise with a shaft of a pressure release cam as the center. At this time, since only the clockwise rotation of the swing lever is transmitted via a one-way clutch to the shaft of the pressure release cam, the clockwise rotation is intermittently transmitted to the shaft of the pressure release cam. As a result of this, the pressure release cam intermittently rotates clockwise, and the pressure release cam pushes away a roller of a displacement frame, so that the pressure roller separates from the hot roller.

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.
