A sheet feeding device includes: a sheet stacker that stores a sheet in a stacked state; a separating air blower that blows air to a sheet from a leading end side in a sheet feeding direction of the stacked sheet; a floating air blower that blows air to a sheet from both sides of a sheet end orthogonal to the sheet feeding direction of the stacked sheet; an attractor that attracts an uppermost sheet that has been floated; a blow direction switcher that changes a blow direction of the floating air blower to an arbitrary direction; and a hardware processor that controls change in the blow direction of the floating air blower by the blow direction switcher in accordance with at least one of a basis weight, a size, and a floating property of a sheet.
