Abstract
When charging an actuator, first, the charging is performed by applying an intermediate voltage lower than a driving voltage which is a target voltage and then charging is performed by applying the driving voltage to the actuator. When discharging the actuator, the discharging is performed by applying the intermediate voltage and then the discharging is performed by applying a zero voltage to the actuator which is charged by the driving voltage. The time for applying the intermediate voltage at a timing of ejecting the ink from the nozzles is shorter than the time for applying the intermediate voltage to the actuator at other timings.
