摘要： A method of a sheet alignment includes carrying a sheet from a sheet discharging port; transferring the sheet on a tray device toward a sheet end regulating device; moving the sheet on the tray device in a width direction orthogonal to the sheet discharging direction for widthwise alignment; and abutting again the sheet on the tray device against the sheet end regulating device while the sheet is in the widthwise alignment. When the sheet on the tray device is transferred toward the sheet end regulating device, the sheet is transferred at a predetermined speed. Before the sheet abuts against the sheet end regulating device, the speed is reduced to provide a conveying force to the sheet without stopping. While the conveying force is continuously applied to the sheet, the sheet is aligned in the width direction to thereby prevent skewing of the sheet relative to the sheet end regulating device.
