PROBLEM TO BE SOLVED: To start the printing of another corresponding face without making a printing paper sheet remain after the printing of a single face is completed when performing double-face printing, in an image forming system in which a plurality of sets of image forming devices which are connected in series along the paper sheet conveyance direction print printing data composed of a plurality of pages.SOLUTION: The image forming system 1 for printing an image based on image data in which the printing data composed of the plurality of pages are applied with image processing in a page order comprises: the first imaging forming device 30A for forming the image on the paper sheet, and the second image forming device 50A which is arranged at the downstream side in the paper sheet conveyance direction with respect to the first image forming device 30A. At the double-face printing, a CPU 33a of a control part 33 discriminates the image data corresponding to the front surface of the paper sheet and the image data corresponding to the rear surface of the paper sheet, and makes the first image forming device 30A print an image based on the image data corresponding to the rear surface of the discriminated paper sheet. A control part 53 makes the second image forming device 50A print an image based on the image data corresponding to the front surface of the paper sheet. |
