Abstract
An electrostatic ink jet recording head has a laminate structure for an electrode assembly disposed in an ink chamber of a head body. The laminate structure includes a first base film, a plurality of patterned recording electrodes, a plurality of patterned control electrodes and a second base film. The recording electrodes and control electrodes are alternately arranged one by one as viewed perpendicular to the laminate. The tips of the recording electrodes are located ahead of the tips of the control electrodes toward the opposite electrode. In operation, the control electrodes located on both sides of a specified recording electrode are applied with a high voltage pulse to eject liquid ink from the meniscus in the vicinity of the specified recording electrode. The ink jet recording head can be manufactured at low costs and with a higher density.
