SHEET PROCESSING DEVICE AND IMAGE FORMING DEVICE

摘要

A sheet processing device (2) is provided with: a shift device (43) that shifts a stack of sheets in the width direction on a processing tray (41); a discharge portion (44) that discharges the stack of sheets from the processing tray (41); a holding tray (34) on which the discharged stack of sheets are held; and a pressing lever (46) that can turn between a first position with the pressing lever (46) abutting on the stack of sheets on the holding tray (34) and a second position where the pressure lever (46) is moved from the first position to the discharge portion (44) side. The discharge portion (44) comprises an upper roller (56) and a lower roller (57). The lower roller (57) abuts the lowermost sheet of the stack of sheets. The upper roller (56) separates upwardly from the lower roller (57) during shifting, while the upper roller (56) approaches the lower roller (57) during discharging. The pressing lever (46) is provided so as to protrude upward of the top of the lower roller (57) at the second position and turns to the second position during shifting.
