Abstract
A postprocessing device is attached to an image forming apparatus. The postprocessing device includes a processing tray, a sheet processor, and a fan. The processing tray is for stacking thereon sheets on which an image has been formed and which is transported from the image forming apparatus. The sheet processor performs predetermined postprocessing on the sheets stacked on the processing tray. The fan forms an air layer between an upper face of the sheets already stacked on the stacking surface of the processing tray and a lower face of a sheet newly placed on the processing tray, by emitting air in a transport direction of the sheet, from an upstream side in the transport direction toward the stacking surface.
