Claim 1
Independent Claim
204 words
AN ELECTROPHOTOGRAPHIC PROCESS INCLUDING A COLOR MASKING OPERATION COMPRISING PROVIDING A PHOTOCONDUCTIVE INSULATOR AS A MAIN PHOTOSENSITIVE ELEMENT AND A SUBSTANTIALLY TRANSPARENT PHOTOCONDUCTIVE INSULATOR AS A TRANSPARENT PHOTOSENSITIVE ELEMENT, WHERE SAID MAIN PHOTOSENSITIVE ELEMENT IS PROVIDED WITH A GROUNDED CONDUCTIVE SUPPORT AND SAID TRANSPARENT PHOTOSENSITIVE ELEMENT IS PROVIDED WITH A TRANSPARENT GROUNDED CONDUCTIVE SUPPORT AND WHERE THE SPECTRUM SENSITIVITY REGION OF SAID TRANSPARENT PHOTOSENSITIVE ELEMENT DIFFERENT FROM THE SPECTRUM SENSITIVITY REGION OF SAID MAIN PHOTOSENSITIVE ELEMENT OR SAID MAIN PHOTOSENSITIVE ELEMENT COMBINED WITH A COLORED FILTER, CHARGING BOTH PHOTOSENSITIVE ELEMENTS WITH THE SAME POLARITY, FACING THE CHARGED SURFACES OF BOTH SAID PHOTOSENSITIVE ELEMENTS TOWARD EACH OTHER SO THAT A SLIGHT GAP EXISTS THEREBETWEEN (1) WITH SAID COLORED FILTER INTERPOSED AND/OR A SUBSTANTIALLY TRANSPARENT INSULATOR INTERPOSED, OR (2) WITH NOTHING INTERPOSED, IMAGE EXPOSING WHILE BOTH SAID PHOTOSENSITIVE ELEMENTS ARE HELD IN REGISTRY FROM THE SIDE OF SAID TRANSPARENT PHOTOSENSITIVE ELEMENTS TO OBTAIN THE ELECTROSTATIC LATENT IMAGES OF REFLECTED IMAGE RELATION ON SAID MAIN PHOTOSENSITIVE ELEMENT AND SAID TRANSPARENT PHOTOSENSITIVE ELEMENT, AND DEVELOPING THE LATENT IMAGE ON SAID MAIN PHOTOSENSITIVE ELEMENT WHILE MAINTAINING SAID REGISTRY BEBTWEEN BOTH SAID PHOTOSENSITIVE ELEMENTS, THE AMOUNT OF TONER DEPOSITED BEING INFLUENCED BY THE LATENT IMAGE ON SAID TRANSPARENT PHOTOSENSITIVE ELEMENT.

AN ELECTROPHOTOGRAPHIC PROCESS INCLUDING A COLOR MASKING OPERATION COMPRISING PROVIDING A PHOTOCONDUCTIVE INSULATOR AS A MAIN PHOTOSENSITIVE ELEMENT AND A SUBSTANTIALLY TRANSPARENT PHOTOCONDUCTIVE INSULATOR AS A TRANSPARENT PHOTOSENSITIVE ELEMENT, WHERE SAID MAIN PHOTOSENSITIVE ELEMENT IS PROVIDED WITH A GROUNDED CONDUCTIVE SUPPORT AND SAID TRANSPARENT PHOTOSENSITIVE ELEMENT IS PROVIDED WITH A TRANSPARENT GROUNDED CONDUCTIVE SUPPORT AND WHERE THE SPECTRUM SENSITIVITY REGION OF SAID TRANSPARENT PHOTOSENSITIVE ELEMENT DIFFERENT FROM THE SPECTRUM SENSITIVITY REGION OF SAID MAIN PHOTOSENSITIVE ELEMENT OR SAID MAIN PHOTOSENSITIVE ELEMENT COMBINED WITH A COLORED FILTER, CHARGING BOTH PHOTOSENSITIVE ELEMENTS WITH THE SAME POLARITY, FACING THE CHARGED SURFACES OF BOTH SAID PHOTOSENSITIVE ELEMENTS TOWARD EACH OTHER SO THAT A SLIGHT GAP EXISTS THEREBETWEEN (1) WITH SAID COLORED FILTER INTERPOSED AND/OR A SUBSTANTIALLY TRANSPARENT INSULATOR INTERPOSED, OR (2) WITH NOTHING INTERPOSED, IMAGE EXPOSING WHILE BOTH SAID PHOTOSENSITIVE ELEMENTS ARE HELD IN REGISTRY FROM THE SIDE OF SAID TRANSPARENT PHOTOSENSITIVE ELEMENTS TO OBTAIN THE ELECTROSTATIC LATENT IMAGES OF REFLECTED IMAGE RELATION ON SAID MAIN PHOTOSENSITIVE ELEMENT AND SAID TRANSPARENT PHOTOSENSITIVE ELEMENT, AND DEVELOPING THE LATENT IMAGE ON SAID MAIN PHOTOSENSITIVE ELEMENT WHILE MAINTAINING SAID REGISTRY BEBTWEEN BOTH SAID PHOTOSENSITIVE ELEMENTS, THE AMOUNT OF TONER DEPOSITED BEING INFLUENCED BY THE LATENT IMAGE ON SAID TRANSPARENT PHOTOSENSITIVE ELEMENT.
Claim 3
Dependent Claim
29 words
An electrophotographic process as in claim 1 where said main photosensitive element is panchromatic and blue, green, and red filters are used respectively to effect a subtractive color process.
Claim 4
Dependent Claim
35 words
An electrophotographic process as in claim 1 where said main photoconductive material is panchromatic and a red filter is used, said transparent photoconductive material is green sensitive, and the color of the toner is cyan.
Claim 5
Dependent Claim
35 words
An electrophotographic process as in claim 1 where said main photoconductive material is panchromatic and a green filter is used, said transparent photoconductive material is red sensitive, and the color of the toner is magenta.
Claim 6
Dependent Claim
37 words
An electrophotographic process as in claim 1 where said main photoconductive material is panchromatic and a blue filter is used, said transparent photoconductive material is red and green sensitive, and the color of the toner is yellow.
Claim 7
Dependent Claim
26 words
An electrophotographic process as in claim 1 where said toner is of the same polarity as that of said latent images whereby reversal development is effected.
Claim 8
Dependent Claim
25 words
An electrophotographic process as in claim 1 where the polarity of said toner is opposite to that of said latent images to effect positive development.
