ABSTRACT:
The invention relates to a printing device for electrophoretic recording by means of electrodes which are relatively movable with respect to an image carrier. Between the image carrier and electrodes, a liquid developer fluid is present in which the electrodes are immersed. Recording takes place under the influence of a control voltage (U.sub.ST) causing adherence of electrophoretic pigment to the image carrier. In order to enable point-like (matrix-like) recording, the surface of the image carrier is electrically conductive and the developer fluid at the area of the electrodes is continuously exchanged to maintain the electrophoretic pigment supply.
