SHEET FOLDING DEVICE, AND IMAGE FORMATION SYSTEM

To provide a sheet folding device having high productivity, and an image formation system.SOLUTION: A first folding processing part 50 for performing first folding processing with respect to a sheet P, and a second folding processing part 70 for performing a second folding processing in a folding direction different from the first folding direction with respect to the sheet P on which the first folding processing has performed, are provided. Further, a plurality of conveyance switching parts 61, 62 capable of conveying the sheet P conveyed from the first folding processing part 50 toward the second folding processing part 70 by switching the conveyance direction, are installed.SELECTED DRAWING: Figure 2 【課題】生産性の高い、シート折り装置、及び、画像形成システムを提供する。【解決手段】シートＰに対して第１折り処理をおこなう第１折り処理部５０と、第１折り処理がおこなわれたシートＰに対して第１折り処理とは異なる折り方向の第２折り処理をおこなう第２折り処理部７０と、が設けられている。そして、第１折り処理部５０から搬送されたシートＰを搬送方向を切替えて第２折り処理部７０に向けて搬送可能な搬送切替部６１、６２が複数設置されている。【選択図】図２
