Abstract

PURPOSE:To eliminate the disadvantage due to adhesion of toners or the like by providing a cylindrical member which is operative to rotate at a high speed in a manner to form a fine spacing between the needle electrodes at the both ends of a recording element. CONSTITUTION:There is provided at the both ends of a dielectric drum acting as a recording element a toller 10 acting as such a cylindrical member as is operative to rotate at a high speed by a roller 9 while being connected to a shaft 7 by means of a bearing 8. A needle electrode 12 attached to a light plate 11 made of plastics is mounted in the vicinity of and in a manner to face the dielectric drum 6. The needle electrode 12 is preferred to be light, e.g., an electrode which is prepared by foaming a resin and by embedding a wire or an electrode which has only its leading end held in a resin in a row while its other portions exposed to the air. As a result, a fine spacing can be held by the use of a boundary film of air which is formed on the surface of the cylindrical member as a result of the high speed rotations thereof. Thus, it is possible to eliminate the disadvantage due to the adhesion of toners or the like.
