method and device for removing unerwuenscht product angezogenem magnetic farbpulver a magnetaufzeichnungsflaeche a magnetschriftdrukkers

摘要

A technique and apparatus for removing electrostatically attracted magnetic toner particles from a recorded surface on which magnetic images are formed for magnetic printing. Magnetic toner powder is applied to a surface having magnetic images recorded thereon, the toner adhering to the recorded areas for subsequent transfer to a writing surface. An electrical discharge path is provided from the recording surface to discharge electrostatically attracted particles spuriously attached to the recorded surface. Spurious particles are thereby removed from the recorded surface and are not transferred to a writing surface, with a result that cleaner and more easily readable printed material is produced.
