Abstract
A sheet feeding apparatus which includes a sheet holder holding at least one sheet to be fed. A pick-up roller feeds the at least one sheet from the sheet holder in a sheet feeding direction. A separating roller is provided at a lower reach of the pick-up roller. This separating roller receives a reverse torque in an opposite direction of the sheet feeding direction through a torque limiter. A feeding roller is provided opposite the separating roller and feeds the at least one sheet from the pick-up roller in the sheet feeding direction. Further, a frictional element is provided to increase a rotational load of the separating roller.
