Xerographic and magnetic image recording and reproducing

Claim 1

IN A METHOD OF REPRODUCING A TWO COMPONENT IMAGE PATTERN COMPRISING FORMING A MAGNETIC LATENT IMAGE OF A FIRST COMPONENT OF SAID IMAGE PATTERN IN A MAGNETIZABLE SURFACE AND FORMING AN ELECTROSTATIC LATENT IMAGE OF THE SECOND COMPONENT OF SAID IMAGE PATTERN IN A PHOTOCONDUCTIVE INSULATING SURFACE AND DEVELOPING SAID MAGNETIC LATENT IMAGE AND SAID ELECTROSTATIC LATENT IMAGE SIMULTANEOUSLY WITH A COMPOSITE ELECTROSTATICALLY AND MAGNETICALLY ATTRACTABLE DEVELOPER; THE IMPROVEMENT OF FORMING SAID MAGNETIC LATENT IMAGE AND FORMING SAID ELECTROSTATIC LATENT IMAGE ON A PLATE HAVING A SINGLE COMPOSITE REPRODUCING SURFACE FORMED OF SEPARATE AND DISTINCT COPLANAR PORTIONS OF PHOTOCONDUCTIVE AND MAGNETIC MATERIALS RESPECTIVELY, BY APPLYING A MAGNETIC FIELD IN IMAGE CONFIGURATION TO SAID SURFACE TO FORM THE MAGNETIC LATENT IMAGE PORTION ON THE MAGNETIC MATERIAL PORTION OF SAID SURFACE, AND EXPOSING SAID SURFACE TO AN IMAGE PATTERN OF LIGHT AND SHADOW AFTER THE APPLICATION OF A UNIFORM ELECTROSSTATIC FIELD THROUGH SAID PLATE, TO FORM THE ELECTROSTATIC LATENT IMAGE PORTION ON SAID PHOTOCONDUCTIVE MATERIAL PORTION OF SAID SURFACE.
