Abstract
A fusing roller regenerating apparatus of a fusing device in an image forming apparatus includes a coating unit coating a fusing roller using a dip coating method to form a regenerated coating layer to a predetermined thickness, and a heating unit including a heating body spaced apart from a surface of the fusing roller by a predetermined distance to harden the regenerated coating layer formed on the fusing roller by the coating unit. A method of regenerating the fusing roller includes injecting a coating liquid into the coating liquid tub through a coating liquid injection portion to form the regenerated coating layer to the predetermined thickness by rotating the fusing roller after the injection of the coating liquid, hardening the regenerated coating layer using the heating body, and discharging a remaining portion of the coating liquid through the coating liquid discharging portion after the hardening of the regenerated coating layer. The fusing roller regenerating apparatus in the image forming apparatus and a method thereof are capable of regenerating a new outer silicone coating layer of the fusing roller when an old outer silicone coating layer is contaminated, damaged or worn out, thereby reducing maintenance costs and waste of resources that are caused by a replacement of the expensive fusing device.
