摘要：
A creasing device that creases sheets on a per-sheet basis and includes: a first member extending perpendicularly to a sheet conveying direction and including a convex blade; a second member extending perpendicularly to the sheet conveying direction and including a concave blade, into which the convex blade is to be fitted; a drive unit that brings the first and the second members into and out of contact with each other, thereby producing a crease in a sheet interposed between the first and the second members; a sheet retainer driven by the drive unit and brought into contact with the second member with the sheet therebetween to retain the sheet across its full width; and a holding unit that holds the sheet retainer in a retaining state during creasing where the contact between the first and the second members starts at one point and develops in one direction.
