Abstract (en)

In a discharge recovery method for an ink jet recording head (1), a recording head having discharge openings for discharging ink therethrough, liquid paths (2) in which recording energy generating members (3) generating energy for discharging the ink through the discharge openings are provided and which communicate with the discharge openings, and a liquid chamber (4) communicating with the liquid paths (2) for supplying the ink to the liquid paths is used to drive heat energy generating (5) means provided in the liquid chamber for generating heat energy for causing a change in the state of the ink in the liquid chamber (4) and creating a bubble, during non-recording, thereby causing the ink to be discharge through the discharge openings.
