Cutting device and image forming system

Abstract

A cutting device includes a cutting unit and a pre-processing unit. The cutting unit performs fore-edge cutting processing and top-edge/tail-edge cutting processing in a state in which a blade inclines toward a paper surface of a booklet. The fore-edge cutting processing is to cut off a first edge part of the booklet parallel to a spine of the booklet. The top-edge/tail-edge cutting processing is to cut off a second edge part of the booklet perpendicular to the spine. Of the top-edge/tail-edge cutting processing, in first top-edge/tail-edge cutting processing in which the blade cuts the booklet from a side opposite to the spine, before the blade abuts the spine, the pre-processing unit makes a cut at a point of the spine along a cutting direction in which the blade cuts the spine, the point where the blade abuts the spine.
