FOLDING APPARATUS

An object of the present disclosure is to provide a folding apparatus capable of properly executing a folding process with reducing obstruction to its operation for folding by rollers conveying a sheet when the sheet is folded keeping the sheet being held on a conveying path. The folding apparatus includes a conveying device having rollers to hold and convey a sheet, and a folding device folding the sheet conveyed by the conveying device, the folding device including a holding part that holds the sheet on a conveying path, and an approximating part that approximates a folding piece of the sheet to a position opposite a held piece of the sheet held by the holding part, the conveying device including a retreating part that retreats the rollers from the conveying path when the sheet is folded by the folding device.
