Electrostatic recording apparatus with improved recording electrode

An electrostatic recording apparatus comprising:

• a recording electrode means and a back electrode means for applying image signals therebetween, wherein said recording electrode and said back electrode are positioned with a predetermined gap therebetween, and wherein said recording electrode has a molded body and stylus electrodes embedded therein;
• a magnetic brush means positioned adjacent a side of said back electrode opposite from said recording electrode means and including a rotatable magnet roller having a plurality of alternate magnetic poles on a surface thereof and a fixed cylindrical sleeve spaced from and concentric with said magnet roller, said magnetic brush means transporting a magnetic toner on said back electrode means positioned adjacent said cylindrical sleeve;
• a recording medium movable through said gap between said recording electrode means and said back electrode means, said recording medium moving through said gap in contact with said recording electrode means and said recording medium being subject to a discharge from said recording electrode means which imparts a charge on a surface of said recording medium corresponding to said image signal;
• and
• a magnetic piece embedded in a tip portion of said recording electrode means, said magnetic piece influencing the magnetic flux paths originating from said magnetic roller and enhancing transfer of said magnetic toner from said back electrode means to said recording medium adjacent said tip of said recording electrode means regardless of the magnetic pole position of said magnetic roller relative to said tip of said recording electrode means.
