ABSTRACT:
An ink jet printer provided with an ink jet print head having a nozzle, an ink channel that is connected to the nozzle, and an electrostatic actuator that is composed of a diaphragm that is provided in a part of the ink channel and an electrode placed outside of the ink channel opposite to the diaphragm. The diaphragm is distorted by means of an electrostatic force generated by applying a first voltage to the electrostatic actuator. A second voltage, different than the first voltage, is applied to the actuator to relax the diaphragm and to discharge ejecting ink droplets from the nozzle.
