PROBLEM TO BE SOLVED: To shorten throughput while suppressing curl amounts of paper sheets when continuously forming images on a plurality of pieces of the paper sheets and discharging them.SOLUTION: An inkjet recording device 1 comprises: a liquid ejection head 4 for ejecting inks to paper sheets; a discharge tray 11 on which the paper sheets applied with printing are stacked; a parameter determination means 81 for reading page numbers of the paper sheets from a printing job; a curl correction factor setting means 82 for setting a standby time of the printed paper sheets; and a curl correction mechanism 2 which is connected to the curl correction factor setting means 82, makes the printed paper sheets wait for only the standby time which is set by the curl correction setting means 82 before the printed paper sheets are discharged by the discharge tray 11, and corrects the curl of the paper sheets. When it is determined that the page numbers of the paper sheets are located at a rear side in the printing job by the parameter determination means 81, the curl correction factor setting means 82 elongates the standby time about the paper sheets compared with the paper sheets whose page numbers are located at a front side in the printing job. |
