Ink jet recording head drive method and ink jet recording apparatus

摘要

The present invention provides an ink jet recording head drive method for applying a drive voltage to an electro-mechanical converter which changes a pressure within a pressure generation chamber filled with ink, so that an ink droplet is ejected from a nozzle communicating with the pressure generation chamber, wherein the drive voltage has a voltage waveform including: a first voltage change process (1) for increasing a volume of the pressure generation chamber so as to pull the ink meniscus at the nozzle opening toward the pressure generation chamber; and a second voltage change process (2) for decreasing the volume of the pressure generation chamber, so as to eject an ink droplet, and wherein the first voltage change process (1) is preceded by a preparatory voltage change process (7) for slightly pulling an ink meniscus from the nozzle opening toward the pressure generation chamber.
