摘要： A fixing unit and an image forming apparatus are provided. The fixing unit applies heat and pressure to a print medium on which a toner image is formed and fixes the toner image on the print medium. The fixing unit includes a heating roller including a heating source, at least two pressurizing rollers which are pressed against the heating roller along an outer circumferential surface of the heating roller, adhesion elastic bodies which elastically press the pressurizing rollers toward the heating roller at first locations of both ends of the pressurizing rollers, and correction elastic bodies which elastically press the pressurizing rollers at second locations of both ends of the pressurizing rollers in the opposite direction of the adhesion elastic bodies. With this structure, the fixing unit forms sufficient fixing nips to reliably fix toner images on the print medium while maintaining a compact structure. Furthermore, this structure increases the life span of the apparatus by minimizing deformation of the pressurizing roller.

摘要： A method and apparatus for controlling a fusing temperature, and an image forming apparatus are provided. In the method of controlling a fusing temperature, power is supplied to a heat source included inside a heat roller at on/off chopping rates determined according to the temperature of the heat roller during a time period in which the temperature of the heat roller is rising, and power is supplied to the heat source at on/off chopping rates which are respectively increased by a predetermined value with respect to the determined on/off chopping rates during a time period in which the temperature of the heat roller is falling. Accordingly, a fusing property can be prevented from degrading in an initial printing process after a cold start occurs in a fusing unit, and thus a first print out time (FPOT) can be reduced.

摘要： A heat roller for a laser printer has a roller pipe, a resistive heat element accommodated in the roller pipe, an internal expanding pipe installed in the roller pipe which restricts the resistive heat element by pushing the resistive heat element toward the roller pipe, caps coupled to both end portions of the internal expanding pipe and provided with electrodes which supply a current to the resistive heat element, a gear coupled to any one of the caps, and a coupling unit which restricts at least one of the caps from slipping along the internal expanding pipe. The heat roller has the enhanced secure coupling between the internal expanding pipe, the roller pipe, the coil and the insulation layer. Accordingly, it is possible to prevent slip off and coil short circuit.
