PROBLEM TO BE SOLVED: To provide an ink-jet recording device capable of ensuring impact accuracy of droplets by correcting curve of the droplets even when the direction of the curve of the droplets discharged from nozzles cannot be expected every time. SOLUTION: A nozzle surface has at least one nozzle A for main droplets to which recording ink is supplied and a plurality of nozzles B which are adjacent to the nozzle for the main droplets and for sub-droplets to which ink for impact correction is supplied. A droplet discharging means discharges the main droplets from the nozzle A for the main droplets and discharges the sub-droplets for impact correction from the nozzles B for the sub-droplets. A droplet charging means charges the main droplets and the sub-droplets with the same polarity. A discharge control means controls the droplet discharging means so that the main droplets and the sub-droplets can exist in the air at the same time while they are flying between the ink-jet head and the impact target. The center of the nozzle A for the main droplets on the nozzle surface is disposed on the point P which satisfies predetermined conditions with respect to the plurality of nozzles B for sub-droplets or in the vicinity thereof.
