Electrophotographic image recording method and apparatus

Abstract From the Canadian patent

An electrophotographic method and apparatus for recording micrographic images permanently on a transparent substrate, in which plural planar reusable electrophotographic plates are mounted for stepwise movement sequentially along a path for a cycle of successive functional operations namely, each plate being sequential charging exposure to form a latent charge image, toning the resulting charge image toned, drying the toned image and contact transferring the toned imaging to a transparent substrate and preparing the plate for reuse. The apparatus includes a rotor for mounting the plates about its circumference and a framework for mounting the functional stations positioned about the rotor …
