摘要： A droplet ejecting apparatus includes: an ejecting section having a plurality of nozzles arranged along an intersecting direction with a transport direction of a recording medium. Each nozzle ejects a main droplet and a sub-droplet smaller than the main droplet consecutively. Each nozzle can change a deflection amount in an ejecting direction of the main droplet along the intersecting direction. A control section performs, in a case where a defective nozzle exists in the nozzles, a control of deflecting the ejecting directions of the main droplets ejected from a nozzle positioned within a predetermined distance from the defective nozzle toward a landing position of a main droplet that should have ejected from the defective nozzle.
