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 voltage to the electrostatic actuator thereby performing printing with ink droplets ejected from the nozzle. The electrostatic actuator driver comprises a timing pulse generator, charge circuit and discharge circuit. The driver controls an amount of charge to be charged to the electrostatic actuator as well as charge rate thereof corresponding to the environmental operating condition of the ink jet printer.
