Abstract

A skew correction device includes: a conveying path through which a booklet formed by folding a sheet bundle is conveyed in a conveying direction; a positioning unit on which a leading-end portion of the booklet in the conveying direction is to abut, the positioning unit being arranged to be able to protrude into and retreat from the conveying path; an abutting unit that pushes a trailing-end portion of the booklet in the conveying direction, thereby moving the booklet toward the positioning unit and causing the leading-end portion of the booklet to abut on the positioning unit; and a pushing force changing unit that changes a pushing force applied by the abutting unit to the booklet to push the booklet against the positioning unit based on a pushing amount of the abutting unit to the booklet.
