Abstract:
A liquid discharge method of a liquid discharge head having a discharge port which discharges a liquid, a channel which communicates with the discharge port and an energy generation unit which is disposed opposite to the discharge port and which generates energy for use in discharging the liquid. The method includes driving the energy generation unit, and then connecting a tip portion of the liquid discharged from the discharge port to the liquid at the discharge port via at least two liquid columns, and cutting the at least two liquid columns to separate the tip portion of the liquid from the liquid at the discharge port.
