Abstract
In a sheet conveying device, sheets having of various width sizes can be adjusted to sheet conveyance reference of a regulating device without moving the regulating device in the lateral direction of a sheet. An image forming apparatus uses two kinds or sheets of different width sizes (the LTR-size and the A4-size). The regulating device is fixed to a position where an LTR-size sheet can be regulated. When performing switchback conveyance of an A4-size sheet, switchback conveying devices convey the sheet while moving it toward the sheet conveyance reference of the regulating device by a predetermined amount.
