  • Patent number: 10838333
    Abstract: An image forming apparatus includes: a fixing member; a holding member; and a cam member. The holding member holds the fixing member such that the fixing member can be displaced between a pressure contact position and a separation position. The cam member is rotatable about an axis in a first direction and a second direction. A distance between a cam surface of the cam member and the axis is reduced in the second direction. A part of the cam surface is in contact with the holding member at a first position in a state where the fixing member is at the separation position, and away from the holding member at a second position in a state where the fixing member is at the pressure contact position. The first direction is opposite to a direction from the first position to the second position about the axis with a smaller central angle.
