1. A fusing roller for fusing an image on a sheet of paper, comprising:
a coil unit resistance heated by a predetermined alternating current and generating an alternating magnetic flux by the alternating current;
a heating roller unit heated by an induced current generated by the alternating magnetic flux;
end caps installed on both ends of the heating roller unit and having electrodes for receiving power from an external power source; and
reduction units formed on both ends of the coil unit to reduce a contact resistance generated when the coil unit contacts the electrodes.
