an electrophotographic member and subsequent high speed discharging as by writing with a fine laser beam upon the limited region of the electrophotographic member the beam being modulated with recordable intelligence from stored digital data the member is mounted for rotary and axial movement relative to both charging unit and an axial movement beam directing unit the member support for the member holds the member in a cylindrical or partially cylindrical form with the photoconductive coating inside the member as a unit and a charging device and writing device as a unit are mounted for relative axial and rotating movement at high speed to enable charging and imaging of the limited regions in a continuous progressive manner application_number US 38262882 A description as stated the invention will be described in connection with the requirements for making a printing plate but it is not so limited the basic invention is believed to be much broader than that covering the method and apparatus for achieving imaging by digitally modulating a beam of radiant energy from information or data carried in a store and writing with the beam upon an electrophotographic film or sheet member that has special attributes that work in concert with the beam the invention revolves around the discovery that the particular electrophotographic member is ideally suited for use with the modulated fine beam when applied in a manner not originally.
