Patent ID: 7527255

Claim:
An image forming apparatus provided with a bookbinding mode for forming images on a plurality of sheets and binding the sheets having the images formed thereon into a book, comprising: a sheet stacking device that stacks a plurality of sheets having images formed thereon as a sheet bundle; a gluing device that applies glue to an end face of the sheet bundle stacked on said sheet stacking device; a wrapping device that bonds a cover sheet to the sheet bundle having the end face thereof glued, to thereby wrap the sheet bundle in the cover sheet; a discharge device that discharges the sheet bundle wrapped in the cover sheet from the apparatus; and a control device that performs control on a bookbinding-mode job such that said control device causes said gluing device to apply glue to the sheet bundle stacked on said sheet stacking device, causes said wrapping device to wrap the glue-applied sheet bundle in the cover sheet, and causes said discharge device to discharge the sheet bundle wrapped in the cover sheet, wherein when the bookbinding-mode job is canceled before the gluing operation is performed by said gluing device, said control device causes said gluing device to apply glue to the sheet bundle stacked on said sheet stacking device before the job is stopped, and causes said discharge device to discharge the glue-applied sheet bundle without causing said wrapping device to wrap the glue-applied sheet bundle in the cover sheet.
