Abstract

See full text

A belt guide and an image forming apparatus having the same are disclosed. The image forming apparatus includes a belt supported by supporting rollers and circulates endlessly. A belt guide is disposed on contact portions between the belt and each of the supporting rollers to prevent a separation of the belt from the supporting rollers. The belt guide is formed in a multi-step concave-convex shape, e.g., a staircase-like shape or a square wave shape. Accordingly, a contact area between the belt and the supporting roller is maximized, thereby effectively preventing wear, separation and color mis-registration of the belt due to meandering thereof.
