Abstract
An endless belt member is suspended in a tensioned manner by a plurality of roller members including a drive roller and a drive motor drives the drive roller member so as to move the belt member in a predetermined direction of travel. A detecting unit detects an amount of displacement of the belt member in a widthwise direction of the belt member, and a correction unit that corrects displacement of the belt member in the widthwise direction. The correction unit corrects the displacement of the belt member in a widthwise direction based on data sampled by the detecting unit every time a drive signal is input to the drive motor a prescribed number of times.
