PROBLEM TO BE SOLVED: To provide a liquid droplet ejector which can form a dot from a treatment liquid on a boundary portion between an image area and a non-image area by performing ejection only a small number of times, and a liquid droplet ejection program. SOLUTION: In this liquid droplet ejector, a recording head ejects a main droplet of the treatment liquid for coagulating an ink liquid, and a separated droplet associated with the main droplet, onto recording paper P, on which an image is to be recorded by using the colored ink liquid, from a nozzle. The liquid droplet ejector controls the recording head so that the main droplet of the treatment liquid and the separated droplet associated with the main droplet can be ejected from the nozzle, and so that a main dot formed from the main droplet on the recording paper P and a separated dot formed from the separated droplet on the recording paper P can be formed on the boundary portion between the image area and non-image one, where recording is to be performed by using the ink liquid, of the recording paper P, respectively.
