摘要：
An image forming apparatus includes a sheet conveyance path, a pair of rollers configured to rotate in a conveyance direction to convey a sheet in the path by holding the sheet, and to reversely rotate in a direction opposite thereto. The reverse rotation is regulated so that the pair of rollers may reversely rotate within a predetermined amount. A sub-unit is releasable from a body of the image forming apparatus.
