Abstract
A rollers separating unit which controls a distance between a heating roller and a pressurizing roller of a fixing unit by an opening/closing of a side cover. The rollers separating unit includes an elastic support member rotatably hinge-coupled to one side of a housing of a fixing unit, to elastically support a roller installed at an outer portion of a main body between a pair of rollers so that the pair of rollers pressurize each other, a first lever rotatably hinge-coupled to one end of the elastic support member, to rotate the elastic support member at a first predetermined angle so that the pair of rollers are separated from each other, and a side cover rotatably hinge-coupled to one side of the main body, to increase a distance between the pair of rollers by operating the first lever.
