A liquid jet head is provided with discharge ports for discharging liquid, liquid flow paths conductively connected with the discharge ports, air bubble generating areas for creating air bubbles in the liquid, and movable members arranged to face the air bubble generating areas, each having a free end in a position relatively near to the discharge port with respect to a fulcrum thereof. This movable member is inclined to position the free end of the movable member to release the air bubble generating area partly to the discharge port so as to enable the tangential line of the free end of the movable member on the side of the air bubble generating area or the extended line thereof to reach directly the discharge port formation area having the discharge port on the liquid flow path side before the creation of air bubble on the air bubble generating area, and with this position as reference, the movable member is displaced following the creation of air bubble on the air bubble generating area. With this arrangement, the liquid discharging efficiency and speed are significantly enhanced as compared with the conventional liquid jet head, and due to more stabilized discharge of droplets from the discharge ports, the quality of recorded images is improved.
