Abstract
A postprocessing device includes a processing tray, a sheet processor, an air blower, an inlet roller pair, and a drive controller. The air blower forms an air layer between an upper face of a first recording sheet already placed on a loading surface of the processing tray, and a lower face of a second recording sheet to be newly placed on the processing tray, by sending air along a transport direction of the recording sheet, from an upstream side in the transport direction toward the loading surface. The drive controller performs an air sending operation, by causing the air blower to send air along the transport direction, before a second recording sheet contacts the upper face of the first recording sheet, and stop sending air before a trailing edge of the second recording sheet in the transport direction passes a nip region defined by the inlet roller pair.
