Abstract
A stylus array for electrographic recording which includes a laminated stack of stylus elements, each separated from the next adjacent stylus element by a non-conductive layer. The stack array of stylus elements is contoured to have a forward end shaped to conveniently fit between the toner shell and a record receiving medium. The rear end of the stylus array is step contoured to provide two levels, to either of which an electrical contact may be made. Preferably the electrical contact is made to one step on alternate ones of the styli and the intermediate styli are connected electrically at the other step thus providing a measure of separation between the electrical connectors. A non-conductive layer is fixed to the lower edge of the stylus array to provide a sliding low-friction surface for engagement with the upper surface of the recording medium.
