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 1/2 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.
