Provided is a sheet-conveying apparatus including: a skew-feeding correction member having an abutting portion which is brought into contact with a conveyed sheet; and a positioning portion positioning the skew-feeding correction member and having a biasing member for biasing the skew-feeding correction member to a direction opposite to a direction to which the skew-feeding correction member rotates by the sheet. The sheet-conveying apparatus is set so that a formula M+MS<MA is established when the sheet is pulled out, wherein a moment generated in the skew-feeding correction member due to a resultant force of tensions to upstream and downstream sides is assumed to be MA, a moment generated in the skew-feeding correction member due to a frictional force between the skew-feeding correction member and the sheet is assumed to be M, and a moment generated in the skew-feeding correction member due to the biasing member is assumed to be MS.
