ABSTRACT:
The electrostatic ink jet head includes a head substrate, a first drive electrode and a second drive electrode which are formed as a double-layer electrode structure for each of the individual electrode units, an ink guide and an insulating substrate in which a through-hole is formed at a position corresponding to the ink guide. In this electrostatic ink jet head, ejection
on-ejection of the ink is controlled according to a superposed voltage obtained by applying voltages of the same polarity to the first drive electrode and the second drive electrode according to image data.
