Abstract
A fixing unit includes a heat roller accommodating a heater and a press roller movable between an operating position in which the recording sheet is nipped by the rollers and a retracted position. A driven gear is provided to one axial end of heat roller, which engages a rotating mechanism for rotating the heat roller. An opening/closing mechanism is arranged to move a first axial end (at the same side as the driven gear of the heat roller) of said press roller to said operating position before moving a second axial end of the press roller to the operating position.
