Abstract
A liquid ejection method wherein a bubble is created in the liquid on a heat generating member provided on a substrate by thermal energy generated by the heat generating member, by which a droplet of the liquid is ejected, the method comprising the steps of contacting to the substrate such a portion of gas-liquid interface between the bubble and the liquid as is not contacted to the substrate by deformation of the bubble: and causing the bubble to be in fluid communication with ambiance simultaneously with or after the contact between the portion and the substrate.
Claims6
A liquid ejection method using a substrate comprising a base plate and a heat generating member provided on the base plate, wherein a bubble is created in liquid on the heat generating member by thermal energy generated by the heat generating member, by which a droplet of the liquid is ejected, said method comprising the steps of:
- contacting of the substrate by a portion of a gas-liquid interface between the bubble and the liquid by deformation of the bubble;
- and
- causing the bubble to be in fluid communication with ambient atmosphere simultaneously with or after the contact between the portion of the gas-liquid interface and the substrate,
- wherein the portion of the gas-liquid interface that contacts the substrate is not always in contact with the substrate.
