An ink jet recording apparatus comprising an ink jet recording head for sucking ink into a pressure chamber (5) and jetting an ink droplet from a nozzle opening (2) by expanding and contracting the pressure chamber (5) by a piezoelectric vibration element (14); the pressure chamber (5) being formed of a nozzle plate (1) and a vibration plate; and a signal generating means for generating signals. The signals include a first signal for contracting the piezoelectric vibration element (14) at a predetermined speed to suck the ink into the pressure chamber (5), a second signal for starting an extension process of the piezoelectric vibration element (14) to splash the ink droplet from the nozzle opening (2) by contracting the pressure chamber (5), a third signal for interrupting the extension process of the piezoelectric vibration element (14) at least once while the extension process is still being performed and a fourth signal for resuming the extension process of the piezoelectric vibration element (14) again after a predetermined period has elapsed. <IMAGE> |
