A cutting device that cuts an edge portion of a sheet bundle having plural sheets stacked, includes: a cutting blade; a paddle provided on a side of the cutting blade, which removes chips attached to the cutting blade by rubbing a side surface of the cutting blade; a controller which controls drive of the paddle. The controller includes a judging section which compares a length of the chips in a direction perpendicular to an edge side of the sheet bundle to be cut by the cutting blade with a predetermined length that has been preset. When the length of the chips is shorter than the predetermined length, the controller makes the paddle to rotate in a predetermined direction, and when the length of the chips is longer than the predetermined length, the controller makes the paddle to rotate in a reverse direction.read more
