Abstract:
A method of ejecting liquid by using a liquid-ejecting head comprising an orifice plate with an orifice for ejecting liquid, a substrate provided substantially parallel to the orifice plate and having energy-generating means for generating thermal energy to be used for generating a bubble to eject the liquid from the orifice, and a liquid-flowing path formed between the orifice plate and the substrate and communicating with the orifice so as to supply the liquid from a liquid chamber to the orifice, said method comprising the steps of:generating the bubble using the energy-generating means for forming a flow of liquid that flows toward the liquid chamber and a flow of liquid that flows toward the orifice in a flow area shifted to a side of the liquid chamber such that an amount of liquid flowing to the orifice becomes substantially uniform around an inner peripheral surface of the orifice at a time of ejecting the liquid; deforming a part of an interface between the liquid and the bubble formed in the liquid so that the interface contacts the substrate; and communicating the bubble with the atmosphere after the step of deforming the interface.
