Liquid development of electrostatic latent images

Claim 1

THE METHOD OF SIMULTANEOUSLY DEVELOPING DURING EXPOSURE IN EXROGRAPHY COMPRISING POSITIONING CLOSE BUT SPACE FROM A UNIFORMLY CHARGED SURFACE OF A PHOTOCONDUCTIVE INSULTING LAYER ON A TRANSPARENT BACKING A DEVELOPER SUPPLY OF ELECTRICALLY CONDUCTIVE INK COMPRISING A HOMOGENEOUS LIQUID SOLUTION AT A RAISED ELECTRICAL BIAS POTENTIAL OF THE SAME POLARITY AS THE CHARGES ON THE SENSITIVE PHOTOCONDUCTIVE INSULTING LAYER AND AT A POTENTIAL ABOUT EQUAL TO THE POTENTIAL OF THE CHARGED PROTOCONDUCTIVE SURFACE, PROVIDING BETWEEN SAID SUPPLY AND SAID CHARGED PHOTOCONDUCTIVE SURFACE FLOW AIDING ELEMENTS IN PHYSICAL CONTACT WITH SAID INK AND SAID CHARGED SURFACE, SAID FLOW AIDING ELEMENTS BEING REGULARLY DISPRESSED AND SUBSTANTIALLY EVENLY DISTRIBUTED THROUGHOUT THE AREA OF CONTACT, EXPOSING SAID PHOTOCONDUCTIVE INSULATING LAYER THROUGH ITS TRANSPARENT BACKING TO A LIGHT IMAGE TO BE REPRODUCED, AND DURING EXPOSURE VARYING THE POTENTIAL APPLIED TO THE INK TO CAUSE THE BIAS APPLIED TO THE INK TO REMAIN ABOUT EQUAL TO THE LEVEL OF CHARGE IN THE PHOTOCONDUCTOR AT POINTS OF LIGHT EXPOSURE CAUSING INK DEPOSITION ON THE SURFACE OF SAID PHOTOCONDUCTIVE INSULATING LAYER IN UNEXPOSED AREAS.

Claim 2

THE METHOD OF SIMULTANEOUSLY DEVELOPING DURING EXPOSURE IN EXROGRAPHY COMPRISING POSITIONING CLOSE BUT SPACE FROM A UNIFORMLY CHARGED SURFACE OF A PHOTOCONDUCTIVE INSULTING LAYER ON A TRANSPARENT BACKING A DEVELOPER SUPPLY OF ELECTRICALLY CONDUCTIVE INK COMPRISING A HOMOGENEOUS LIQUID SOLUTION AT A RAISED ELECTRICAL BIAS POTENTIAL OF THE SAME POLARITY AS THE CHARGES ON THE SENSITIVE PHOTOCONDUCTIVE INSULTING LAYER AND AT A POTENTIAL ABOUT EQUAL TO THE POTENTIAL OF THE CHARGED PROTOCONDUCTIVE SURFACE, PROVIDING BETWEEN SAID SUPPLY AND SAID CHARGED PHOTOCONDUCTIVE SURFACE FLOW AIDING ELEMENTS IN PHYSICAL CONTACT WITH SAID INK AND SAID CHARGED SURFACE, SAID FLOW AIDING ELEMENTS BEING REGULARLY DISPRESSED AND SUBSTANTIALLY EVENLY DISTRIBUTED THROUGHOUT THE AREA OF CONTACT, EXPOSING SAID PHOTOCONDUCTIVE INSULATING LAYER THROUGH ITS TRANSPARENT BACKING TO A LIGHT IMAGE TO BE REPRODUCED, AND DURING EXPOSURE VARYING THE POTENTIAL APPLIED TO THE INK TO CAUSE THE BIAS APPLIED TO THE INK TO REMAIN ABOUT EQUAL TO THE LEVEL OF CHARGE IN THE PHOTOCONDUCTOR AT POINTS OF LIGHT EXPOSURE CAUSING INK DEPOSITION ON THE SURFACE OF SAID PHOTOCONDUCTIVE INSULATING LAYER IN UNEXPOSED AREAS.
