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.

In the powder recording method of the present invention, the surface of the recording medium is faced to a magnetic drum coated with a color-coated magnetic drum, and a back electrode is arranged on the back surface of the recording medium. And then, there is an opening 1-1 that can pass without 1 (with U poles on both the front and back of the body and is colored).
A slit electrode (and a slit electrode with the surface facing the recording body) is installed between the magnetic tram and the recording body, and a slit electrode is installed between the magnetic tram and the back electrode of 1~Electric voltage (apply voltage between the front and back electrodes treated as 4) to Surin 1 electrode 1 engineer λ) surface electrode and the back I

The magnetic field created by the magnetic core 3a is N pole and S pole, and the magnetic field in the rectangular direction on the surface is N between these. , Since the S pole is shaped like an arc, there is also a uniform distribution of 20.
Since the W mind is fixed, the fields i'J'i that stand radially (become magnetic cyranos) are fixed, one of which is l.
