摘要： A method and apparatus for driving a belt is provided. Included is a method and apparatus for searching for a home position of a steering roller for adjusting a position of the belt in a widthwise direction of the belt and placing the steering roller in the home position. The steering roller is moved from the home position to a balance point, in which an amount of variation of the belt in the widthwise direction is less than a predetermined value, or moved to a position of the steering roller that corresponds to a previously driven final position of the belt. The belt is driven in this state such that the amount of initial weaving of the belt is reduced. Thus, an amount of initial weaving of the belt when the belt is driven can be minimized such that a time to obtain images with suitable registration can be greatly reduced.
