A binding processing device includes: a needle binding unit that forms a needle binding portion that binds a paper bundle using a needle; a needleless binding unit that forms a needleless binding portion that binds the paper bundle without using a needle; and a plurality of exit rolls that exit the bound paper bundle. A distance between the needleless binding portion and a center of the plurality of exit rolls is equal to or longer than a distance between the needle binding portion and the center.
