摘要： 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.

摘要： A contact shock dampening and development nip forming apparatus for developers includes a unit to dampen a contact shock and to form a development nip installed on both ends of a developing roller to be disposed between a photosensitive body and the developing roller. Accordingly, the contact shock dampening and development nip forming apparatus absorbs shocks applied to the photosensitive body from the developing roller upon changing the developers, to thereby protect the photosensitive layer of the photosensitive body and extend the lifespan of the photosensitive body. The apparatus also maintains a thickness of the development nip to thereby obtain a steady image quality, even though the developing roller and/or the photosensitive body may be formed of solid substances.

摘要： An electrophotographic printer including a pre-erasing unit. The pre-erasing unit includes a pre-erasing lamp to irradiate light, and a pre-transfer erasing lens to induce the light generated from the pre-transfer erasing lamp to the photosensitive drum, movably installed such that it moves to an erasure position at which the pre-transfer erasing lens is close to the photosensitive drum for erasure, and moves to a retracted position spaced apart from the photosensitive drum so as not to interfere therewith when the photosensitive drum unit is being mounted or dismounted. The pre-erasing unit may further include an elastic member to provide elasticity in a direction in which the pre-transfer erasing lens moves to the retracted position.
