Abstract
A sheet processing apparatus includes a processing tray, a pushing member, and a movable guide. One or more sheets to be processed are placeable on the processing tray for sheet processing. The pushing member is configured to push an edge of the one or more sheets on the processing tray on an upstream side in a sheet conveying direction, by moving along a surface of the processing tray in the sheet conveying direction. The movable guide is movable to a sheet pressing position at which a distance between the surface of the processing tray and the movable guide is equal to or less than a height of the pushing member above the surface of the processing tray. The movable guide is at the sheet processing position when the pushing member moves along the surface of the processing tray in the sheet conveying direction.
