ABSTRACT:
A method of ink jet recording wherein thermal and electric energies are applied to a liquid coloring agent, such as ink, to jet the ink toward a recording member, such as paper. A plurality of spaced apart electric heating resistor and lead electrodes are used to heat the ink and are in direct contact with the ink which has a high electrical resistivity, e.g., a volume resistivity of at least about 10.sup.6 .OMEGA..multidot. cm. Also, there may be used a plurality of spaced apart electric field forming electrodes to apply an electric field to the ink having sufficient electrical resistance to prevent leakage across the electrodes.
