Abstract
Abstract A seamless flexible photoreceptor device which comprises a conductive substrate made up of an elastomeric material formed in the shape of a continuous belt with the elastomer containing a second phase which results in electrical conductivity. A photoconductive layer overlays and is bonded to the substrate. The photoconductive layer comprises a polymeric matrix of an electrically insulating elastomeric resin containing an interlocking network of photoconductive material in the form of continuous chains which pass through the photoconductive layer thickness. The photoconductor is present in a volume concentration of from about 1 to 15 percent by volume of the binder layer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
A FLEXIBLE PHOTORECEPTOR MEMBER COMPRISING: A. A CONDUCTIVE SUBSTRATE COMPRISING AN ELASTOMERIC MATERIAL FORMED IN THE SHAPE OF A CONTINUOUS BELT, SAID ELASTOMER CONTAINING A SECOND PHASE WHICH RESULTS IN ELECTRICAL CONDUCTIVITY; AND B. A PHOTOCONDUCTIVE LAYER OVERLYING AND BONDED TO SAID SUBSTRATE, SAID PHOTOCONDUCTIVE LAYER COMPRISING A POLYMERIC MATRIX OF AN ELECTRICALLY INSULATING ELASTOMERIC RESIN CONTAINING THEREIN AN INTERLOCKING NETWORK OF PHOTOCONDUCTIVE MATERIAL IN THE FORM OF CONTINUOUS CHAINS WHICH PASS THROUGH THE PHOTOCONDUCTIVE LAYER THICKNESS SAID PHOTOCONDUCTIVE BEING PRESENT IN A VOLUME CONCENTRATION FROM ABOUT 1 TO 15 PERCENT BY VOLUME OF SAID BINDER LAYER, WITH THE OUTER SURFACE OF SAID LAYER COMPRISING ELASTOMERIC RESIN MATERIAL.
