Electrostatic ink jet recording apparatus and method of producing the same

摘要

In an electrostatic ink jet recording apparatus for ejecting toner contained in an insulative solvent with an electrostatic force, a record head includes record electrodes formed on a substrate by vapor deposition or application. The record electrodes are physically and electrically separated from each other by grooves each having at least two widths and at least two depths along their respective lengths. The record head has high quality and great mechanical strength and can be produced stably with high accuracy.
