PURPOSE:To remove accumulated toner and to form a stable image for a long period by providing a means which moves a magnetic wire for toner removal not only in the width direction of a recording medium, but also at right angles to the direction in the front of a magnet. CONSTITUTION:When the center of a pulley is at the lowermost position H, the wire 12 is at positions 12a and 12b, but as the center of the pulley rotates in a direction K, the position of the wire moves in a direction F'; when the center of the pulley reaches the uppermost position J from the position H after a half turn, the wire 12 is at positions 12c and 12d. When the pulley further rotates in the direction K, the wire 12 moves in a direction F to the positions 12a and 12b. At this time, a pulley opposite the pulley 15 cross the magnet 8 moves similarly. Thus, the center position of the pulley rotates in the direction K and then the wire 12 reciprocates between the positions 12a and 12c, and 12b and 12d in areas above and below a recording electrode 7 nearby the front surface of the magnet 8 to remove uniformly toner on the surface of the magnet. |
