ABSTRACT:
An ink jet recording method includes the steps of providing an ink jet recording head having a plurality of discharge openings for discharging ink, a plurality of liquid passageways for holding ink and a plurality of heat generating members. Each of the heat generating members corresponds to a liquid passageway and each heat generating member has a pair of electrodes for driving the heat generating member individually and the electrodes and corresponding heat generating member form a U-shaped wiring portion. The recording head may be manufactured using a cutting process. A voltage is applied to selected pairs of electrodes for driving selected heat generating members individually for providing thermal energy to the ink in the liquid passageway for abruptly forming a bubble and discharging ink from the discharge opening and recording on a recording medium.
