Abstract
A method for discharging ink from a discharge port using a liquid jet recording head having the discharge port for discharging liquid, a liquid flow path communicating with the discharge port, a liquid discharge heat generating element provided in the liquid flow path to apply thermal energy for discharging the liquid to the liquid with bubble generation and a fluid resistance element provided upstream of the liquid discharge heat generating element in the liquid flow path. A bubble generating region is used as the fluid resistance element and a movable member is provided facing the bubble generating region and having a free end, the movable member being shiftable upon bubble generation at the region. The method includes the step of generating a bubble by driving the liquid discharge heat generating element and generating the bubble and shifting the movable member by the fluid resistance element. Also discloses are a liquid discharge head, head cartridge, and recording apparatus which perform the method.
