Abstract
Disclosed herein is a driving method of a liquid drop ejecting head in which an oscillatory wave is imparted to a liquid accommodated in a pressure chamber using an electromechanical transducer, which is driven by applying a predetermined driving waveform to the electromechanical transducer, thereby discharging a liquid drop from a nozzle to record an image. The driving method comprising: detecting an environmental temperature, and expanding and/or contracting the driving waveform to be applied to the electromechanical transducer, in a voltage axial direction and a time axial direction, in accordance with the detected environmental temperature, and applying the resulting driving waveform to the electromechanical transducer. Also disclosed is adjusting the waveform of a reverberation adjustor portion of the driving waveform, which adjusts a residual oscillation of the liquid, in accordance with the detected environmental temperature.
