A printing and binding system and method utilize an electrophotographic apparatus for performing a printing operation so that a plurality of booklets can be simultaneously printed and bound even if the quantity to be printed is not large. Rolled paper is cut in a pre-treatment portion i a direction in which the rolled paper is supplied, into sizes each corresponding to a desired booklet so as to prepare cut paper sheets, then the same pages of booklets of a number which can be printed are simultaneously printed on the cut paper sheets in a printing portion, and then the next pages of the booklets are sequentially printed on the next cut paper sheets. After the pages of a plurality of booklets which can be printed simultaneously have been printed, the printed paper sheets for a plurality of the booklets are conveyed to a post-treatment portion so as to be cut into individual booklets so that desired booklets are bound. If the required number of the booklets has not been bound, the aforesaid steps are repeated. The system thus constituted enables a plurality of booklets to be printed simultaneously and also enables the time taken to bound the booklets to be shortened.
