A liquid droplet ejecting head has a nozzle, a driving element which ejects a liquid droplet from the nozzle by being driven, a storing unit, a driving waveform generating unit, and a supplying unit. The storing unit respectively stores plural driving waveforms, which are for timewise driving a driving element in accordance with an amount of a liquid droplet, as plural digital signals each converted into binary numbers expressing a voltage level of the driving waveform and a duration period of the voltage level. The driving waveform generating unit generates plural driving waveforms on the basis of the plural digital signals. On the basis of image data, the supplying unit selects a driving waveform to be supplied to the driving element from among the plural driving waveforms, and supplies a selected driving waveform to the driving element.
