Abstract
The present disclosure relates to a fusing system for fusing toner to a recording medium. The fusing system includes a fuser roller including a metal layer, a pressure roller in contact with the fuser roller, and an external induction heating element. In addition, the disclosure relates to a method for heating a fuser roller of a fusing system including the steps of positioning an external induction heating element in close proximity to the outer surface of the fuser roller, delivering high frequency current to a coil of the external induction heating element to create a magnetic flux, and directing the magnetic flux toward the fuser roller so as to induce eddy currents within a metal layer of the fuser roller that generate heat within the roller.
