Powder recording method

Abstract

Abstract PURPOSE:To form a visible image directly on a recording medium by using a colored magnetic powder with a high reliability without lowering of resolution by a method in which a colored magnetic powder electricaly charged is injected through the opening of a slit electrode onto a recording medium and adhered. CONSTITUTION:A voltage 7 is applied between a magnetic drum 3 and an electrode 12 according to an image signal to implant negative charge to a powder at the tip of a magnetic brush. The powder is attracted by the electrode 12 side, injected onto the recording medium 4 side through the hole 14 of a slit electrode 10 by an acceleration electric field in electrodes 12 and 13, and further accelerated by acceleration electric field between electrodes 13 and 6, thus permitting the powder to be exactly attracted by the surface of the recording medium 4.
