PURPOSE:To maintain a stuck amount of the magnetic fluid toner at a fined value and maintain constantly the optimum condition of the rise by a method wherein a feed device consisting of magnets thereby the magnetic fluid toner is fed from the storage to the support element is provided. CONSTITUTION:A number of styli 1 consisting of a strong magnetic material are disposed to constitute the multistylus. Close to the multistylus tip, a magnet 2 is mounted to magnetize the stylus. One end of a magnet 3, which feeds the magnetic fluid toner, is connected with the end of the magnet 2, and the other end of the magnet 3 is introduced within the storage tank 4 of the magnetic fluid toner. The liquid level of the tank 4 allows to maintain constantly a fixed level. The magnet 3 shows the magnetic pole direction as shown in the figure to suck the magnetic fluid toner. The stuck amount of the toner or stylus tip may be adjustable by height H up to the liquid level within the tank 4 from the stylus tip, enabling to maintain a fixed optimum stuck amount. |
