Abstract
An image forming apparatus includes an image forming unit and a belt conveyance apparatus. The belt conveyance apparatus includes a transfer belt, a tension roller, a movement mechanism, and a drive unit. A toner image on an image bearing member is transferred to the transfer belt in tension from the tension roller. The movement mechanism moves the tension roller to apply tension to, and release tension from, the transfer belt. The drive unit is disposed in a width direction and drives the transfer belt. The movement mechanism includes an attachment portion disposed on a side opposite the drive unit in the width direction and to which a handle member that operates the movement mechanism is detachably attached. The movement mechanism is configured such that the belt conveyance apparatus is attached to an image forming apparatus body in a state in which the handle member is detached from the attachment portion.
