Abstract
A liquid ejection head, a liquid ejection apparatus, and a liquid ejection method are capable of sufficiently suppressing the thickening of a liquid in an ejection orifice. The liquid ejection head includes a pressure chamber, a channel in which a liquid is caused to flow through the pressure chamber, an ejection orifice communicating with the pressure chamber, and an ejection energy generation element configured to eject the liquid in the pressure chamber from the ejection orifice. A meniscus of the liquid is formed at an end portion of the ejection orifice communicating with the pressure chamber.
