Abstract

PURPOSE:To obtain a recording picture having a high quality, by providing an electromagnetic field for generating an AC magnetic field in the vicinity of a rising magnet, so that magnetite of magnetic ink accumulated on the surface of the rising magnet has regular concentration. CONSTITUTION:A rising magnet 7 is arrayed by one to plural needle electrodes 2 formed in one line, and a permanent magnet is used. Magnetic ink passes through a feed route 3, passes through the rising magnet 7, reaches the tip of the needle electrode 2, and ink is jetted from the tip of the needle electrode 2 in accordance with a picture signal applied to a gate electrode. An electromagnet 12 is provided in the vicinity of the rising magnet, vibrates magnetite which is apt to be accumulated on the rising magnet by generating an AC magnetic field, and serves for holding normal concentration.
