A droplet ejection head drive method includes (1) associating multiple nozzles with ranks corresponding to weights of droplets ejected from the nozzles, (2) generating drive waveforms for driving actuators of the nozzles and correcting the weights of the droplets to a predetermined weight, for each of the ranks, and (3) supplying the drive waveforms corresponding to the ranks of some of the nozzles selected according to drawing data, to actuators of the selected nozzles and ejecting droplets each having the predetermined weight from the selected nozzles onto a target.
