    • PROBLEM TO BE SOLVED: To prevent a tray ascending/descending moving body from overrunning and being damaged, when an ascending/descending tray on the paper ejection side of a first post-processing device is detached and then a second post-processing is connected to start its drive. SOLUTION: The image forming system comprises an image forming device A, the first post-processing device and the second post-processing device. The first post-processing device includes: the ascending/descending tray 127 disposed on the paper ejection side of the first post-processing device so as to be ascendable/descendable; the moving body 175 movable while supporting the ascending/descending tray 127; an ascending/descending drive means 170 by which the moving body 175 is driven so as to ascend/descend; and a post-processing control means 20 for controlling the ascending/descending drive means 170. When a drive start operation is performed to connect the second post-processing device after the ascending/descending tray 127 of the first post-processing device is detached, the post-processing control means 20 exerts control so as to hinder the ascending/descending operation of the moving body 175 by the ascending/descending drive means 170 of the first post-processing device.
