Abstract
A heat fixing roller in an electrophotographic recording system provides a high degree of radiating efficiency and reduces the amount of time it takes for the heat fixing roller to achieve a temperature necessary to perform a printing operation. The heat fixing roller has a heat lamp installed along a center axis within an interior portion of the heat fixing roller. A plurality of hollowed-out heat conduits extend outwardly in a radial manner from the heat lamp to provide a path through which heat generated by the heat lamp can radiate to rapidly increase the temperature of an outer surface of the heat fixing roller.
