PURPOSE:To obtain high magnetic flux density atop of a recording electrode by clamping plural electrodes which constitute a recording electrode array with magnets having the same polarity opposite a recording medium across insulating coatings and magnetic material plates, and covering tip parts of the magnetic material plates with nonmagnetic bodies. CONSTITUTION:Numbers of recording electrodes 7 which are impressed with the voltage of an image signal generator 9 are arrayed in the axial direction of the recording medium composed of a conductive layer 1a and a dielectric layer 1b opposite the recording medium, thus constituting the recording electrode array. The recording electrodes 7 are coated with the insulator 13 and further clamped with identical-polarity parts N (or S) of the magnetic material plates 12 and magnets 8. Parts of the magnetic material plates 12 which project from the magnets 8 are coated with nonmagnetic materials 15. Consequently, the magnetic plates 12 are extended to the tips of the recording electrode 7 and the napping of toner on the magnetic material plates is reduced while the magnetic flux density atop the electrodes 7 is increased; and the installation of a toner removing and conveying means is facilitated. |
