Abstract

A liquid ejection apparatus includes: a circuit control device including switches of which first ends are connected to pressure generating elements; a voltage waveform generating device configured to generate a voltage waveform to be supplied to second ends of the switches; and a switch control device which causes the switches to close and open. The voltage waveform has a waveform such that, when the switch is caused to close and open so that a portion of the voltage waveform is applied to the pressure generating element, a droplet is ejected from a nozzle corresponding to the pressure generating element to which the portion of the voltage waveform has been applied, whereas when a whole of the voltage waveform is applied to the pressure generating element, no droplet is substantially ejected from the nozzle corresponding to the pressure generating element to which the whole of the voltage waveform has been applied.
