Abstract
A feeding device to feed a conveyed medium stacked on a stacker, includes a first suction unit, a second suction unit, and third suction units. The first suction unit includes a suction chamber; a suction fan to exhaust air from the suction chamber; and a first driver to rotate the suction fan. The suction units are disposed above the conveyed medium stacked on the stacker. The second suction unit includes a rotary fan including a board and a plurality of walls extending from the board; and a second driver to rotate the rotary fan. The second suction unit generates a vortex flow directed to the conveyed medium. The plurality of third suction units is disposed in a direction perpendicular to a conveyance direction of the conveyed medium and attracts ends of the conveyed medium in the direction perpendicular to the conveyance direction.
