Fusing equipment of image forming apparatus

Abstract

A direct heating type of fusing equipment of an image forming apparatus includes a fusing roller that has a supporting layer formed inside of the fusing roller, a separating layer formed on an outermost portion of the fusing roller, and a heating layer formed between the supporting layer and the separating layer to supply heat; a thermistor being in contact with an outermost surface of the fusing roller to detect a temperature of the surface of the fusing roller; and a pressing roller pressing a printing paper against the fusing roller while rotating together with the fusing roller and being in contact therewith. The heating layer includes a hot wire wound around an outer circumference of the supporting layer; an insulating material formed between the supporting layer and the hot wire; and an insulation resilient layer disposed in a first gap formed between windings of the hot wire created after the winding of the hot wire and also disposed in a second gap formed between the hot wire and the separating layer.
