Abstract
A sheet feeding device includes a sheet storing portion storing sheets stacked on a stacking surface thereof; a feeding roller feeding each of the sheets by rotating while being in contact with a topmost one of the sheets; a support member having a support surface that supports downstream-side part, in a sheet feeding direction, of the sheets and, at the time of sheet feeding, being movable perpendicularly to the stacking surface while lifting the downstream-side part of the sheets with the topmost sheet kept in contact with the feeding roller; and a stopper member configured to come into contact with leading ends of some sheets to be fed by the feeding roller and to stop sheets other than the topmost sheet. The support surface of the support member slopes upward, with respect to the stacking surface, toward a downstream side in the sheet feeding direction.
