ABSTRACT:
A skew of a print medium sheet generally occurs when the sheet is fed to an image-forming area in an image-forming apparatus, for example, an electronics image-forming printer, from a pile of such sheets. An apparatus according to the present invention is provided with a plurality of pairs of feed rollers between the pile and the image-forming area, and a skew of a sheet is corrected every time the sheet comes in contact with each pair of rollers which are not rotating for a predetermined time, so that even a large skew can be corrected by the time the sheet reaches the image-forming area.
