ABSTRACT:
A thermal-electrostatic ink jet recording head is formed of two spaced-apart insulating substrates with an electrostatic field forming electrode and an array of electric heating elements in the slit between the substrates. The heating elements are paired and each of the adjacent heating elements of a pair joined by a common electrode, with each heater having an independent electrode connectable to a switching circuit for selectively heating portions of the ink under the influence of an electrostatic field to cause ink in the heated portions to be jetted. The common electrode preferably is U-shaped with each of its free ends connected to the inner ends of the adjacent electrodes of a pair.
