摘要： An image forming apparatus includes a belt-rotating unit, a meandering-correction unit, and an attach-detach control unit. The belt-rotating unit rotates an endless belt. The meandering-correction unit corrects meandering of the belt. The attach-detach control unit relatively moves the belt and an abutting member such that a surface of the belt abuts against or detaches from the abutting member. The surface of the belt is abutted against the abutting member before the belt attains a constant rotating speed.

摘要： A belt traveling unit includes an endless belt, a drive roller and a correction roller, a driving unit, a correction unit, a contact member, a position detector and a regulating member. The endless belt is spanned between a plurality of rollers. The driving unit rotates the drive roller to drive the belt. The correction unit adjusts a tilt angle of the correction roller to correct drifting of the belt in the width direction thereof. The contact member is rotatable in conjunction with traveling of the belt in the width direction thereof. The position detector detects a position of the contact member to detect a position of the belt in the width direction thereof. The regulating member is located at a position where the position detector does not misdetect the position of the belt when the contact member rotates.

摘要： In a belt device, a first detecting unit detects a widthwise displacement of a belt, and a correcting unit corrects displacement of the belt in the width direction during a period starting from turning power on and ending with completion of drive preparation of the belt based on the widthwise displacement. Moreover, a second detecting unit detects 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 detects that the belt has displaced by an amount that is greater than the threshold.
