| Zusammenfassung: | A relay conveyance device (4) includes a relay conveyance path (50) arranged between an image forming apparatus (2) and a post processing device (3) to convey a sheet from the image forming apparatus (2) to the post processing device (3), two reversing units (41) reversing a surface side and a back-face side of the sheet, and a control device (45) controlling conveyance of the sheet on the relay conveyance path. The relay conveyance path includes two reverse paths (54a, 54b) respectively passing through the two reversing units (41), a branch section (53) branching into the two reverse paths (54a, 54b) at an upstream side, and a confluence section (55) joining the two reverse paths (54a, 54b). The control device (45) controls the branch and confluence sections (53, 55) to convey the sheet while alternately switching the two reverse paths (54a, 54b), measures an interval time between the sheets passing through the confluence section (55), and controls conveyance of the sheet in the two reverse paths (54a, 54b) so as to uniformize the interval time. |
