Abstract:
1. A fixing device comprising: a fixing member used to fix an image onto a recording medium; a pressure member having one end portion and another end portion in an axial direction thereof, the pressure member being rotatably provided, the pressure member being pressed against the fixing member so as to apply a pressure to the recording medium; a first cam having an outer circumferential surface and a projecting portion provided on the outer circumferential surface of the first cam, the first cam being attached to the one end portion of the pressure member, the first cam being rotatable in a circumferential direction of the pressure member, the first cam being rotated in one direction so as to cause the projecting portion thereof to apply a pressure toward the fixing member, thereby causing the one end portion side of the pressure member to move in a direction in which the one end portion side of the pressure member is separated from the fixing member; a connecting member connected to the first cam on the one end portion side of the pressure member, the connecting member extending toward the other end portion side of the pressure member; and a second cam having an outer circumferential surface and a projecting portion provided on the outer circumferential surface of the second cam, the second cam being attached to the other end portion of the pressure member, the connecting member being connected to the second cam, the second cam being rotatable in the circumferential direction of the pressure member, the second cam being rotated in the one direction by receiving a drive force from the connecting member, which is interlocked with the first cam rotated in the one direction, so as to cause the projecting portion thereof to apply a pressure toward the fixing member, thereby causing the other end portion side of the pressure member to move in a direction in which the other end portion side of the pressure member is separated from the fixing member, wherein, before the first cam and the second cam are rotated in the one direction, the projecting portion of the second cam is positioned downstream of the projecting portion of the first cam in the one direction.
