Abstract
When a sheet is fed, a feeding roller is rotated in the direction opposite to the direction in which the sheet is fed to draw out the uppermost sheet from a separation claw, and then the sheet is fed in such a manner that the feeding roller is rotated in the direction in which the sheet is fed to feed the drawn out sheet along the upper surface of a separation claw. When the sheet is fed, a curvature formation portion curves downward both ends in the width direction of the second and subsequent sheets to integrally lower pressing portions for pressing both ends in the width direction of the sheet along with the curved sheets and to separate the pressing portions from the uppermost sheet, thereby preventing the leading end of the uppermost sheet from catching the pressing portions.
