Abstract
A sheet bundle stored in a sheet storage portion is pushed from a predetermined folded position with a first pushing plate, and the sheet bundle is normally conveyed along with the first pushing plate and plunged into a nip between first folding rollers to make a fold. The first folding rollers are reversely rotated while the first pushing plate is retreated, and the sheet bundle with the fold is reversely conveyed and returned to the sheet storage portion. Then, a second pushing plate pushes the sheet bundle, conveyed through a U-shape conveyance path, from a backside of the fold to reversely fold the sheet bundle, and the sheet bundle is completely folded. Therefore, the sheet bundle having good appearance can be realized in good bundle folding processing.
