To improve productivity without increasing the scale of a device even when the end part of a sheet bundle to perform folding end part processing remains inside an area to load the next sheet bundle.
When a length in a carrying direction of a following folding bundle is such a length that a conveying direction upstream end remains inside the area of a storage part 803 when it is tentatively stopped for the processing of a folding end part, the following folding bundle for which the processing of the folding end part is completed is conveyed by folding conveying roller pairs 811 and 812 until the conveying direction upstream end gets out of the area of the storage part 803 before completing the return of a preceding folding bundle already loaded on a folding bundle tray 840 to a second loading position on the conveying direction upstream end by conveyor belts 844 and 845.
