Patent ID: 7445305

Claim:
A droplet ejection apparatus comprising: a plurality of ejection components that include a first ejection component and a second ejection component which are connected to each other so as to be capable of being mutually charged and discharged, whereby the discharge from the second ejection component is utilized as the charge into the first ejection component; and a control component, wherein a driving signal is applied to each of the plurality of ejection components, a first driving signal to be applied to the first ejection component has a charging process, a second driving signal to be applied to the second ejection component has a discharging process, the control component makes a control so that a charge timing of the first driving signal and a discharge timing of the second driving signal overlap each other, the control component determines a group of the first ejection component for applying the first driving signal and the second ejection component for applying the second driving signal from among the plurality of ejection components, and changes at least one of the timings of the first driving signal and the second driving signal so that the charge timing and the discharge timing overlap each other in the determined group, the second driving signal is a driving signal by which droplets are not ejected from the second ejection component to which the second driving signal is applied, and the control component changes the timing of the second driving signal.
