A post-processing apparatus for performing post-processing on a sheet having an image formed thereon, the post-processing at least including case bookbinding by using paste, the apparatus including: a paste applicator having a paste application member and configured to supply paste to coat a back of a sheet bundle with the paste; a pressurization member for pressing a cover onto the back of the sheet bundle with the paste coated thereon; and a controller configured to receive information relating to a cover gutter setting on the sheet bundle and to perform control over the paste applicator and the pressurization member, the controller being configured to cause, in a guttered cover setting, the paste to overflow in a larger amount from the back of the sheet bundle toward a gutter than an amount of overflow in a non-guttered cover setting based on the information relating to the cover gutter setting.

Systems, apparatuses, and methods are provided for providing a rotatable perfect binding separated step solution configured to maximize efficiency for one-off book printing. The multi-clamp binding apparatus includes a rotatable body, a plurality of fixed operation stations associated with the rotatable body, and a plurality of clamps coupled to the rotatable body. Each of the clamps may retain at least one workpiece. The rotatable body may rotate each of the plurality of clamps to one or more of the plurality of fixed operation stations. In operation, a book block is received at an in-feed location of the perfect binding apparatus. The book block is stored within a holding apparatus of the perfect binding apparatus. The book block is then rotated between a plurality of fixed operation stations. At least one operation is performed upon the book block at each of the plurality of fixed operation stations.

Provided is an image forming apparatus configured to form an image on a sheet. A case binding apparatus is configured to cut predetermined sides of a sheet bundle formed by binding a plurality of sheets to perform bookbinding. The case binding apparatus includes a cutting-waste box configured to collect cutting waste produced by the cutting and a cutting-waste full load detection sensor configured to detect a fully loaded state of the cutting-waste box with the cutting waste collected in the cutting-waste box. When the sheet onto which the image is to be formed is not a last sheet in the sheet bundle, the image forming apparatus does not interrupt image formation processing in response to the fully loaded state of the waste box detected by the detector when an order of the sheet in the sheet bundle is smaller than a predetermined order.
