ELECTROGRAPHIC ELEMENT PROVIDED WITH ELECTRICAL CONNECTION MEANS Abstract of the Disclosure An electrographic element comprising an electri- cally insulating support, an electrically conductive layer overlying the support, and an electrically insulating photo- conductive layer overlying the conductive layer, is provided with electrical connection means adapted to establish electri- cal connection between the conductive layer and a grounding or biasing member which engages a surface of the element while the element is in motion. The electrical connection means comprises a region of dispersed particulate electrically- conducting material within a non-recording portion of the element which extends from the surface of the element into contact with the conductive layer. This region defines on the surface of the element an elongated stripe which is longi- tudinally disposed in the direction of motion of the element and which encompasses an elongated longitudinally disposed groove. To form the region of dispersed particulate electri- cally-conducting material, an elongated groove extending from the surface of the element at least to a position proxi- mate to the conductive layer is formed in the element and an imbibable composition comprising the particulate material is then applied to the surface of the element as an elongated stripe which encompasses the groove. The groove serves to promote the imbibition of the particulate material into contact with the conductive layer so as to form an electrical path from the conductive layer to the stripe on the surface of the element and thus provide electrical connection with the grounding or biasing member which engages the stripe.
