Abstract

An electrostatic recorder for applying electrical charges, in image configuration, upon a movable image recording member, the recorder including a stylus electrode array and a counter electrode array which electrode arrays are aligned with one another on opposite surfaces of the image recording member and are positioned so as to extend across the direction of movement of the image recording member. The counter electrode array comprises a base member supporting a plurality of electrically conductive traces thereon, each extending substantially in the direction of movement of the recording member. The conductive traces are interconnected by a layer of resistive material, and contact pads are connected to periodically spaced conductive traces so as to apply electrical potentials to spaced regions of the counter electrode array. Those conductive traces located intermediate the periodically spaced conductive traces are electrically floating when electrical potentials are applied to the spaced conductive traces.
