<p>In a belt device, a first detecting unit (80) detects a widthwise displacement of a belt, and a correcting unit (13) corrects displacement of the belt in the width direction during a period starting from Lurning power on and ending with completion of drive preparation of the belt based on the widthwise displacement. Moreover, a second detecting unit (88) defects whether the belt has displaced in the width direction by an amount that is greater than a threshold, and a belt stopping unit stops running of the belt when the second detecting unit (88) detects that the belt has displaced by an amount that is greater than the threshold.</p> |
