Abstract
A droplet ejection apparatus includes an ejecting unit, a driving unit and a correcting unit. The ejecting unit has plural droplet ejection portions that include pressure chambers containing a liquid, ejecting portions ejecting droplets, and driving elements that cause the ejecting portions to eject droplets of a droplet volume in accordance with a driving signal. The driving unit generates a driving signal according to ejection data and applies the driving signal with a predetermined voltage application cycle period. Between different volume droplets, when a difference of the ejection time, from ejection until adhering to a medium, or from application of the driving signal until adhering to the medium, exceeds ½ the voltage application cycle period, the correcting unit corrects the ejection data according to the ejection time difference such that the voltage application timing of the driving signal is corrected by an integer multiple of the voltage application cycle period.
