LIQUID DROPLET EJECTING APPARATUS, LIQUID DROPLET EJECTION CONTROLLER, AND LIQUID DROPLET EJECTION METHOD

PROBLEM TO BE SOLVED: To facilitate correction of a striking position deviation between liquid droplets of different droplet volumes exceeding an impression period without lengthening the impression period. SOLUTION: When a drive signal is impressed by the impression period preliminarily set for a driving element which changes the pressure in a pressure chamber so as to eject liquid droplets of the droplet volume conformed to ejection data from an ejecting part that ejects the liquid droplets according to a change of the pressure in the pressure chamber by communicating with the pressure chamber where the liquid is contained, if an ejection time after the liquid droplet is ejected from the ejecting part before the liquid droplet adheres to a medium to be ejected with the liquid droplet, or after the drive signal is impressed to the driving element before the liquid droplet is ejected from the ejecting part and adheres to the medium is different exceeding 1/2 of the impression period between a plurality of kinds of the liquid droplets of different droplet volumes ejected to the medium, the ejection data is corrected so that an impression timing of the drive signal to the driving element is corrected by every impression period according to a time difference of the ejection times.
