PURPOSE:To eliminate the vibration of a recording electrode and to form a fog- free image with high density by arranging an intense magnetic plate between a magnet roller for fog removal and a magnet provided to the recording electrode. CONSTITUTION:The fog removing roller 12 which removes toner from a no-image part incorporates a magnet 13 and the magnet 8 which applies a magnetic field between the recording electrode 7 and a recording medium 1 is fixed to the recording electrode 7. Then, the intense magnetic plate 16 is attached to the roller 12 between both magnets 13 and 8. Therefore, the magnet 13 is shielded by the magnetic plate 16 and the magnet 8 never vibrates through the magnetic field operation of the magnet 13 even when the magnet 13 is put close to the magnet 8 and rotates at 1,000rpm, so the electrode 7 does not vibrate either. Consequently, the disorder of the image is eliminated and the fog-free image is formed with high density. |
