Abstract:
An electrostatic ink jet recording head comprising:a head body including a substrate, a laminate overlying said substrate, and a top cover plate overlying said laminate, said laminate including a first base film adjacent said top cover plate, a plurality of recording electrodes formed on a lower surface of said first base film, a second base film adjacent said substrate, and a plurality of control electrodes formed on an upper surface of said second base film, said laminate and said top cover plate defining therebetween an ink chamber for receiving liquid ink, and a front edge of said top cover plate and a front edge of said first base film defining an ink jet slit; andan opposite electrode disposed opposite to said ink jet slit,wherein said recording electrodes and said control electrodes are arranged alternately and extend in a direction perpendicular to said ink jet slit and extend substantially parallel to each other, andwherein each of said recording electrodes has a tip located ahead of a tip of each of said control electrodes such that any said tip of said recording electrodes is closer to said opposite electrode than any said tip of said control electrodes.
