ABSTRACT:
An ink jet printing apparatus comprises a nozzle head including, orifices for ejecting ink particles, pressure chambers each having a piezoelectric element for applying a pressure wave to ink in the chamber and each communicating with corresponding one of the orifices and an ink chamber communicating with the pressure chambers, and electrical signal applying device for applying an electrical signal to selected one or ones of the piezoelectric elements to produce the pressure waves. The electrical signal applying device applies a main electrical signal pulse to the selected one or ones of the piezoelectric elements for inducing rises of the pressure waves and applies a sub-electrical signal pulse for suppressing the pulsations of the pressure waves a predetermined time interval after the main electrical signal.
