Sheet feeding device

A sheet feeding device comprising:

• a sheet supporting portion configured to support sheets;
• an air blowing portion configured to blow an air toward an upstream end from a downstream end of the sheets supported by the sheet supporting portion in a sheet feeding direction;
• a feeding belt configured to feed and suck the uppermost sheet of the sheets to which the air is blown by the air blowing portion;
• and
• an upstream suction portion disposed upstream of the feeding belt in the sheet feeding direction and configured to suck the uppermost sheet,
• wherein the feeding belt includes a first suction area opposing the uppermost sheet and configured to suck the uppermost sheet, and the upstream suction portion includes a second suction area opposing the uppermost sheet and configured to suck the uppermost sheet, and
• wherein in a widthwise direction perpendicular to the sheet feeding direction, a width of the second suction area is narrower than a width of the first suction area.
