PURPOSE:To eliminate resiliency which operates between magnets, increase the density of magnetic flux atop a group of recording electrodes, and secure the space where a toner removing conveyance system is provided by arranging a magnetic body plate between magnetic poles of the magnets arranged across the recording electrode group. CONSTITUTION:An iron wire with a 20mum diameter is used as a recording electrode 7 and 3,360 pieces of recording electrodes are arranged over a 210mm. width. An insulating coating 13 of an adhesive is formed on the electrodes 7, which are fixed on an iron plate 12. The iron plate 12 extends to the overall width of the electrodes 7. A recording medium 1 faces the recording electrodes 7 almost at right angles. The electrodes 7 is sandwiched between the two magnets 8 arranged so that the same poles face each other, resiliency is eliminated because of the presence of the plate 12 and the magnets 8 rather attract each other across the plate 12. Further, the density of magnetic flux atop of the electrodes becomes larger than when the plate 12 is not provided, so the distance between the magnets 8 and recording medium 1 is set to >= about 1cm, and the space for the system which conveys toner staying near the magnets 8 is secured. |
