Abstract:
A sheet post-processing apparatus for performing post-processing on a sheet having an image formed thereon. A stapling section or a scoring section performs processing on a sheet and a sheet bundle. The upper limit value of a sheet count of sheets processable at a time by the post-processing unit is equal to N (N is an integer). A buffer path performs buffer processing for retaining a conveyed sheet, placing the retained sheet and a sheet following the retained sheet one on the other, and conveying the superimposed sheets as a sheet bundle. A CPU controls the buffer path the stapling section or the scoring section such that when the processing is being performed on the sheet or the sheet bundle, the buffer processing is performed on a following sheet, and that the processing is performed on each sheet bundle having been subjected to the buffer processing.
