摘要： A liquid discharge apparatus includes a liquid discharge head and a head drive controller. The liquid discharge head includes an actuator including an electromechanical transducer element. The head drive controller controls the liquid discharge head. The head drive controller includes a drive waveform generator and a voltage updater. The drive waveform generator generates a drive waveform to be applied to the electromechanical transducer element. The voltage updater updates a voltage value of the drive waveform to a larger value with an elapse of time. The voltage updater sets a time interval of update of the voltage value to be longer as a number of times of the update is greater.
