Abstract
Abstract In an electrostatographic recording member comprising at least: (1) an electrically-insulating substrate; (2) an electrically-conductive intermediate layer overlying a first surface of said substrate; and (3) an electrically-insulating outer layer overlying said conductive layer, said outer layer containing a photoconductive material or being composed of a dielectric material of high volume resistivity; The improvement comprising a combined means for accurately positioning said recording member during imaging thereof and for establishing an electrical ground connection to said intermediate conductive layer, said combined means comprising at least two separate holes through said recording member in a non-image area thereof and a conductive lacquer coating on the inner surface of at least one of said holes, said holes being adapted to receive protrusions during imaging to accurately position said recording member and said conductive lacquer being in electrical contact with the exposed intermediate conductive layer on the inner surface of said hole.

Claim 1
Independent Claim
149 words
In an electrostatographic recording member comprising at least: (1) an electrically-insulating substrate; (2) an electrically-conductive intermediate layer overlying a first surface of said substrate; and (3) an electrically-insulating outer layer overlying said conductive layer, said outer layer containing a photoconductive material or being composed of a dielectric material of high volume resistivity; the improvement comprising a combined means for accurately positioning said recording member during imaging thereof and for establishing an electrical ground connections to said intermediate conductive layer, said combined means comprising at least two separate holes through said recording member in a non-image area thereof and a conductive lacquer coating on the inner surface of at least one of said holes, said holes being adapted to receive protrusions during imaging to accurately position said recording member and said conductive lacquer being in electrical contact with the exposed intermediate conductive layer on the inner surface of said hole.
Claim 2
Dependent Claim
149 words
In an electrostatographic recording member comprising at least: (1) an electrically-insulating substrate; (2) an electrically-conductive intermediate layer overlying a first surface of said substrate; and (3) an electrically-insulating outer layer overlying said conductive layer, said outer layer containing a photoconductive material or being composed of a dielectric material of high volume resistivity; the improvement comprising a combined means for accurately positioning said recording member during imaging thereof and for establishing an electrical ground connections to said intermediate conductive layer, said combined means comprising at least two separate holes through said recording member in a non-image area thereof and a conductive lacquer coating on the inner surface of at least one of said holes, said holes being adapted to receive protrusions during imaging to accurately position said recording member and said conductive lacquer being in electrical contact with the exposed intermediate conductive layer on the inner surface of said hole.
Claim 3
Dependent Claim
