Abstract:
A belt drive device for an image forming apparatus includes a belt, a roller, a roller drive member, a state detector and a controller. The roller drive member drives the roller that entrains the belt. The state detector detects a state of the belt. The controller identifies a specific portion of the belt based on the state detected by the state detector, and controls the roller drive member to stop the belt so that the specific portion lies at a predetermined position.
