The present invention relates to a sheet conveying apparatus, comprising: a conveying portion conveying a sheet; a shutter member having an abutting surface for abutting the sheet to correct skew feeding; a biasing member for biasing the shutter member to position at a first position where the leading end abuts against the abutting surface; and a support mechanism which movably supports the shutter member to move in an order of the first position, a second position to which the shutter member moves by the sheet against biasing from the biasing member, and a third position where the shutter member abuts the sheet and stands by to move to the first position when a trailing end of the sheet passes the shutter member, while keeping the abutting surface facing upstream.
