PURPOSE:To stably form a high-resolution recorded image without abrading a recording head by forming the surface of the partof a recording electrode which extends to a recording part of a magnetic material. CONSTITUTION:The exposed surfaces of respective recording electrode lines 20a are respectively coated with magnetic layers 20d made of the magnetic conductive material, which is excellent in abrasion resistance, such as nickel or 'Permalloy(R)', so that the recording electrode EL is constituted. Therefore, most of magnetic fluxes of traveling-wave magnetic field which is formed on the surface of a jacket member 15A are regulated so that they may be focused on the electrode EL and extended toward a cylindrical electrode 5 side, and magnetic toner (d) forms bristles along the focused magnetic fluxes, thereby forming a toner chain which extends orderly. Since the magnetic toner (d) hardly exists between the adjacent electrodes EL and EL, a leak phenomenon is surely prevented and the distinct toner recorded image whose resolution is high and whose density is high is stably formed. Furthermore, the abrasion of the recording electrode EL is prevented because the magnetic layer 20d becomes a protective layer. |
