1. Imaging apparatus comprising a substantially flat shuttle electrode supported for travel between park and turn positions, at least one imaging electrode supported adjacent the path traveled by the shuttle electrode and having means for coupling to a voltage source to establish an electric field between said shuttle and imaging electrodes, exposure means for exposing photoelectrophoretic ink on one of said electrodes to electromagnetic radiation to form an image as the shuttle electrode travels past the imaging electrode from photoelectrophoretic ink exposed to electromagnetic radiation and subjected to electric field;

  • and, elevator means for moving said shuttle and imaging electrodes to mutually operative positions as the shuttle electrode travels past the imaging electrode.
