ABSTRACT:
A fixing unit, used for fixing images on a recording sheet, includes a heat roller accommodating a heater, and a press roller movable between a retracted position and an operating position. The heat roller is rotated by a driving mechanism. A moving mechanism opens and closes a gap between the press roller and the heat roller by moving the press roller between the retracted position and the operating position. An assist gear rotates the press roller in a predetermined direction when the opening/closing mechanism moves the press roller toward the operating position.
