ABSTRACT:
An ink jet recording head is configured to jet small ink droplets for forming high-quality dot images. The ink jet recording head comprises ink jetting orifices from which ink droplets are jetted, and ink paths connected to said ink jet orifices. The ink paths are filled with ink and equipped with energy applying members for applying energy to the ink in said ink paths on demand so that ink droplets are jetted from said ink jetting orifices.
