Abstract

A driving device for a liquid ejection head including an actuator configured to eject liquid stored in a pressure chamber through a nozzle, includes a drive circuit configured to generate a drive signal for the actuator of the liquid ejection head, the drive signal including one or more drop waveforms for ejecting one or more droplets of the liquid through the nozzle. The drive circuit is further configured to arrange the one or more drop waveforms in a rear-justified manner such that an end timing of a final drop waveform is the same among drive waveforms for ejecting different numbers of droplets.
