ABSTRACT:
A fusing roller and a fusing apparatus using the same are provided. The fusing roller includes a coil unit resistance heated by a predetermined alternating current, and an alternating magnetic flux is generated by the alternating current. A heating roller unit is heated by an induced current generated by the alternating magnetic flux. End caps are installed on both ends of the heating roller unit and have electrodes for receiving power from an external power source. Reduction units are formed on both ends of the coil unit to reduce contact resistance generated when the coil unit contacts the electrodes.
