Abstract:
A liquid jet recording method comprising the steps of:providing a recording liquid which is normally liquid;providing a liquid jet recording head having a liquid passage and a liquid outlet, said liquid passage having a heat generating resistor,wherein the following conditions are satisfied:S1.gtoreq.S2/3, andS2.gtoreq.S3/3where S1 is an area of the heat generating resistor, S2 is a projected area, onto a surface having the heat generating resistor, of said liquid passage between said liquid outlet and said heat generating resistor, and S3 is a cross-sectional area of said liquid outlet;applying thermal energy to the recording liquid in the liquid passage and thereby causing film boiling of the liquid to produce a bubble for ejecting the liquid through the liquid outlet, while said liquid jet recording head is not heated, except by said heat generating resistor;permitting the bubble to communicate with an atmosphere adjacent the liquid outlet, wherein the bubble does not block said liquid passage when the bubble communication with the atmosphere occurs; andrefilling the liquid passage after the ejecting of the liquid.
