Abstract
A toner image fixing device includes a driven fixing roller drivingly connected to a driving source and a rotatably mounted follower fixing roller. The follower fixing roller is mounted on a movable supporting member which is mounted for free movement between a contacting position at which the follower fixing roller is kept in press contact with the driven fixing roller and a non-contacting or non-pressing position at which the follower fixing roller is kept out of press contact with the driven fixing roller. A press-contacting control mechanism selectively holds the movable supporting member at the contacting position and the non-contacting position. The press-contacting control mechanism includes a positioning member connected to the movable supporting member via a spring and an actuating device for selectively holding the positioning member at an operating position and a non-operating position. When the positioning member is moved to the operating position, the movable supporting member is moved to the contacting position via the spring. When the positioning member is moved to the non-operating position, the movable supporting member is moved to the non-operating position via the spring.
