摘要： Disclosed are fusing unit, an image forming apparatus employing the fusing unit and a method of controlling the same. The fusing unit disclosed herein includes a heating belt having a non-conductive outer surface and a pressing roller that allows a print medium to be in a pressing contact with the outer surface of the heating belt. A negative voltage or a positive voltage is selectively applied to the pressing roller based on the presence of a print medium between the pressing roller and the heating belt.

摘要： An image forming apparatus includes a fixing belt which is rotatably mounted, a support roller which is in contact with an inner surface of the fixing belt to support the fixing belt, a press member which pressurizes a portion of the fixing belt toward a paper, and a press roller which is in pressure contact with the support roller and the press member, the fixing belt being positioned between the press roller and the support roller and between the press roller and the press member. At least one of the support roller and the press roller has a concave shape such that a diameter of both ends of the at least one of the support roller and the press roller is larger than a diameter of a middle portion, and the press member is formed with a curved portion which is convexly formed at a middle portion of the at least one of the support roller and the press roller.
