A sheet feeding device (10) has a conveying belt (21), a first roller (22), a second roller (23), a support portion (24), a takeout section (3). The conveying belt is wound along the first roller and the second roller, and the first roller forms a conveying terminal portion (31) of the conveying belt in the first conveying direction. The second roller forms a slope portion (32) of the conveying belt that slopes downward toward the conveying terminal portion. The support portion supports each of a plurality of sheets dropped from the conveying terminal portion in an upright position, at a position more downward in the vertical direction than the conveying terminal portion. The upper sheet, out of the sheets which are overlapping on the conveying belt in the vertical direction, is arranged to relatively deviate toward a downstream side in the first conveying direction than the lower sheet.
