ABSTRACT:
A capacitive load driving circuit that supplies driving voltage to a capacitive load includes a driving voltage waveform generating unit. The driving voltage waveform generating unit, at times of charging or discharging of the capacitive load, generates a driving voltage waveform in which potential applied to the capacitive load varies stepwise from a first potential to a second potential during a predetermined time period.
