    • A control electrode assembly is provided between a corona discharger and an electrostatic recording medium. The control electrode assembly has a pair of conductive electrodes interposing therebetween a insulating layer having a through hole extending from the upper conductive electrode to the lower conductive electrode. Selected one of the conductive electrodes is grounded through a change-over switch, which connects the selected electrode to the ground and disconnects the other non-selected electrode from the ground to electrically open it. Corona ions from the corona discharger charge the electrically opened conductive electrode to establish an electric field within the through hole. The corona ion current passing through the through hole can be modulated by operating the change-over switch to control the direction of the electric field established within the through hole in accordance with an image signal to form an electrostatic image on a recording medium.
    • 控制电极组件设置在电晕放电器和静电记录介质之间。 控制电极组件具有一对导电电极,介于其间具有从上导电电极延伸到下导电电极的通孔的绝缘层。 所选择的一个导电电极通过转换开关接地,该转换开关将所选择的电极连接到地,并将另一未选择的电极从地面断开,以将其电打开。 来自电晕放电器的电晕离子对导电电极进行充电,以在通孔内形成电场。 可以通过操作转换开关来调节通过通孔的电晕离子电流,以根据图像信号控制在通孔内建立的电场的方向,以在记录介质上形成静电图像。
