Abstract
A sheet feeding device includes a supporting portion supporting sheets, an air blower blowing 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 belt feeding and sucking the uppermost sheet of the sheets to which the air is blown by the air blower, and an upstream suction portion disposed upstream of the feeding belt in the sheet feeding direction and sucking the uppermost sheet. The belt includes a first suction area opposing the uppermost sheet and sucking the uppermost sheet. The upstream suction portion includes a second suction area opposing the uppermost sheet and sucking the uppermost sheet. 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.
