PURPOSE:To prevent a plural number of ink drops from jetting from an electrode plate, by a method wherein a large number of the electrode plates, mounted at an inner surface of an ink jet port in an electrostatic acceleration type ink jet recorder, is formed such that the width is narrowed at a point of the jet port. CONSTITUTION:The electrostatic acceleration type ink jet recorder records such that a large number of electrode plates 3' are placed at an internal surface of an ink jet port 1 of a recording head, and ink in the jet port 1 is jetted through the selective application of a high-voltage pulse between said electrodes 3 and a facing electrode 4 at the side of a record paper 5. In said ink jet recorder, the point (a spot facing the record paper 5) of the electrode plate 3' is reduced in the width. |
