Claim Text:
1. A fixing device comprising: a plurality of contact bodies including a first contact body and a second contact body and having peripheral surfaces that are in contact with each other, the contact bodies applying a pressure to a recording medium by allowing the recording medium to pass through a space between the peripheral surfaces, thereby fixing an unfixed image on the recording medium; a pressing member that applies a force to the first contact body so that the peripheral surface of the first contact body is pressed against the peripheral surface of the second contact body, the pressing member being movable between a first position at which the pressing member is in contact with the first contact body and a second position at which the pressing member is separated from the first contact body; a first urging member that urges the pressing member to apply a force to the first contact body through the pressing member; a guide member having a guide groove that receives a portion of the first contact body to control a direction in which the first contact body moves; a second urging member that is interposed between the pressing member and the guide member and that urges the guide member to apply a force to the first contact body through the guide member; and a changer that selectively changes a position of the pressing member between the first position and the second position.
