    • 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.
    • 图像形成装置中的定影装置的定影辊再生装置包括:涂布单元,使用浸涂法涂布定影辊,以形成预定厚度的再生涂层;以及加热单元,其包括与 定影辊的表面预定距离,以通过涂覆单元使形成在定影辊上的再生涂层硬化。 再生定影辊的方法包括通过涂布液注入部将涂布液喷射到涂液槽中,通过在注射涂布液之后旋转定影辊将再生涂层形成为预定厚度,使再生涂层硬化 层,并且在再生涂层硬化后,通过涂布液排出部排出剩余部分的涂布液。 图像形成装置中的定影辊再生装置及其方法能够在旧的外部硅氧烷涂层被污染,损坏或磨损时再生定影辊的新的外部硅氧烷涂层,从而降低维护成本和浪费 由更换昂贵的定影装置引起的资源。

    • A printing media supply device for use in an image forming apparatus includes a printing media supply cassette adapted to receive a stack of printing media. A pick-up roller picks up the printing media stacked in the printing media supply cassette. The pick-up roller has a pick-up member for picking up the printing media, and a rotation member for supporting the pick-up member. The rotation member has a buffer surface formed by cutting a portion of a leading edge portion thereof away. The buffer surface may be formed so as to expose side surfaces of the pick-up member. The pick-up roller applies a substantially uniform pressure to the printing media even when there is a large quantity of printing media stacked in the printing media supply cassette, and thereby minimizes multifeeding of the printing media. Accordingly, the supply of printing media is stable, improving the printing media supply efficiency.
    • 用于图像形成装置的打印介质供应装置包括适于接收打印介质堆叠的打印介质供应盒。 拾取辊拾取堆放在打印介质供应盒中的打印介质。 拾取辊具有用于拾取打印介质的拾取构件和用于支撑拾取构件的旋转构件。 旋转构件具有通过切割其前缘部分的一部分而形成的缓冲表面。 缓冲表面可以形成为露出拾取构件的侧表面。 即使在打印介质供应盒中堆积有大量的打印介质,并且从而最小化打印介质的多重进纸,拾取辊对打印介质施加基本均匀的压力。 因此,印刷媒体的供应稳定,提高了印刷媒体的供应效率。
