Abstract

PURPOSE:To obtain the titled device with high resolution, high speed and low cost by making a signal forming part a triple layered structure where a ferromagnetic material thin layer, an insulator thin layer and a resistor thin layer are superposed in order from the lower part and further by coating the end surface of the ferromagnetic material thin layer with the insulator thin layer or the resistor thin layer. CONSTITUTION:A line electrode 9 is wound like a spiral on a rotatable cylindrical drum 8 and in close vicinity to it in a plane parallel to an axis of the cylindrical drum 8, a thin film layer 11 having the end surface 10 that is a signal forming part is placed. For a distance between the line electrode 9 and the thin film layer 11 about 50-150mum is appropriate from the contact, and the shorter the distance, a dot size becomes smaller, but when both are contact, abrasion causes trouble. Further, by placing, in colse vicinity to or in contact with such as electrostatic printing signal generating part, an electrostatic recording material 2 at the front part of said generating part and by preparing a rear electrode 12 in the opposite side of said generating part, voltage is applied between the line electrode 9 and the rear electrode 12.
