Abstract
A recording head is provided with a slit-like issuing opening, and a plurality of divided electrodes which have a very small width are disposed in or adjacent to the slit-like issuing opening in very closely spaced apart relationship. An opposite electrode is disposed in front or back of a recording paper. The ink which is filled in the slit-like issuing opening and is adjacent to the divided electrode which is selected is emitted as a drop by the potential difference between the ink adjacent to said selected divided electrode and the opposite electrode.
