ABSTRACT:
A roller apparatus includes a rotating roller, a bushing frictionally supporting the rotating roller, a frame having a bushing hole into which a bushing is inserted and supporting the bushing, and a grounding member interposed between the bushing and the frame and grounding the bushing by press contacting with the bushing when the bushing is inserted into the bushing hole. Thus, the roller apparatus effectively grounds a bushing.
