摘要

A sheet feeding device, which is configured to feed stacked sheets one by one in a sheet feed direction, is provided with a sheet tray configured to accommodate the stacked sheets, a feed-out roller protruded from the sheet tray and configured to feed the stacked sheets from the sheet tray, a feed-out nip member arranged above and opposite to the feed-out roller, the feed-out nip member being configured to contact an uppermost sheet of the stacked sheets and bias the sheets toward the feed-out roller, a separation unit located on a downstream side, in the sheet feed direction, of the feed-out roller, the separation unit separating a lowermost sheet from the stacked sheets fed by the feed-out roller, and a friction member configured to contact the uppermost sheet of the stacked sheets at a position different from a position where the feed-out nip member contacts the uppermost sheet.
