A feeding device includes: a sheet material housing configured to allow a plurality of sheet materials to be stacked; an upper surface suction unit that sucks a top sheet material by generating negative pressure at a position facing the upper surface of the top sheet material; a sheet material conveying unit that causes the top sheet material, which is sucked up, to be sucked onto a conveying member and conveys the top sheet material; and a lower suction unit that exerts a suction force downward onto the sheet materials that are positioned near the top sheet material, wherein a suction force exerted on the top sheet material downward by suction of the lower suction unit is smaller than a suction force exerted on the top sheet material upward by suction of the upper surface suction unit and is larger than adhesion between the sheet materials.
