PROBLEM TO BE SOLVED: To improve the productivity of image forming work by narrowing the intervals of forms fed in continuous image formation and to improve the productivity of image forming work by narrowing the intervals of forms even in both side printing in the interleaving system. SOLUTION: In the case of both side printing in the interleaving system, a means is provided which changes the time required for re-feed in which a form fed from a form storage part 1 and passes a junction A between a re-feed line 29 and a form carrying line 4 is returned to the junction A again through an image forming part 2 and the re-feed line 29, and this time required for re-feed is made shorter to narrow the intervals of forms, thereby enhancing the productivity of image forming work at the time of both side printing in the interleaving system. |
