Abstract
An improved counter electrode assembly for an electrostatic recorder in which the recorder applies electrical charges, in image configuration, upon a movable image recording member by means of a stylus electrode array and a counter electrode assembly aligned with one another and between which the image recording member may be moved. Both the stylus electrode array and the counter electrode assembly are positioned so as to extend transversely to the direction of movement of the image recording member. The counter electrode assembly comprises a support member, an elastica sheet member anchored to the support member and bowed toward the stylus electrode array, and an electrically resistive member urged by the elastica sheet toward the stylus electrode array.
