Abstract

The present invention provides a sheet conveying apparatus, and an image reading apparatus and an image forming apparatus having such a sheet conveying apparatus, in which skew correction of a sheet can be effected with high accuracy. A sheet convey means is provided at an upstream side of a skew correction means for correcting skew-feed of a sheet, and the sheet convey means is shifted by a shift means in a direction substantially perpendicular to the sheet conveying direction. A control means drives the shift means to shift the sheet convey means pinching the sheet to be skew-corrected by the skew correction means by a distance corresponding to a sheet skew amount on the basis of sheet skew amount information from a sheet skew amount detection means for detecting a skew amount of the sheet, thereby shifting the sheet in a skew correction direction.
