发明名称 SHEET PROCESSING DEVICE AND IMAGE FORMING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a sheet processing device for creasing a sheet while reducing a crease positional displacement, and to provide an image forming apparatus with the sheet processing device.SOLUTION: A sheet processing device includes a pair of pushing plates 62 and a pair of sheet receiving rollers 66. The pushing plates push a sheet conveyed and stopped astride a pair of auxiliary resist rollers 51 and a pair of resist rollers 52 arranged sequentially from an upstream side to a downstream side in a direction crossing a sheet conveyance direction to crease the sheet. The sheet receiving rollers receive the sheet pushed by the pushing plates between the pair of auxiliary resist rollers and the pushing plates. The pushing plates and the sheet receiving rollers are arranged closer to the pair of auxiliary resist rollers than to the pair of resist rollers. The pair of resist rollers can stop rotation to hold the sheet so that the sheet pushed by the pushing plates cannot be pulled out. The pair of auxiliary resist rollers are rotatable in a direction which allows the sheet pushed by the pushing plates to be pulled out.
