ABSTRACT:
A sheet finisher includes a conveyance member which conveys a sheet to an ejection direction, a sheet ejection section having paired rollers for ejecting the conveyed sheet by nipping the sheet by the paired rollers, and a control section for controlling the conveyance member and the sheet ejection section to separate the paired rollers from each other when conveying the sheet. After a front end portion of the sheet in the ejection direction passes a nipping position of the paired rollers, the control section makes the paired rollers press-contact with each other, nip and reconvey the sheet, and eject the sheet out of the finisher. The control section further controls the conveyance member and the sheet ejection section to temporarily release the press-contact of the paired rollers during reconveyance of the sheet to remove a sag from the sheet to then make the paired rollers press-contact with each other again, and to eject the sheet out of the finisher by nipping the sheet.
