Zusammenfassung:c a ba b c The present invention provides a sheet conveying apparatus and an image forming apparatus capable of preventing occurrence of skew feeding when correcting sheet lateral deviation. A pair of lateral-shift correcting rollers to correct positional deviation in the sheet width direction based on positional deviation quantity detected by a lateral-registration detection sensor is controlled after controlling a skew feeding correcting roller so as to correct sheet skew feeding based on skew-feeding quantity at a sheet leading edge detected by skew-feeding detection sensors and . Then, skew-feeding quantity of the sheet leading edge to be detected by the skew-feeding detection sensors and for correcting skew feeding of the next sheet is adjusted with skew-feeding quantity at the sheet trailing edge detected by the lateral-registration detection sensor after positional deviation in the sheet width direction is corrected.
