Liquid injection recording method in which the liquid droplet volume has a predetermined relationship to the area of the liquid discharge port

摘要

In a liquid injection recording method, recording is effected in such a manner that the relation between the minimum cross-sectional area So of droplet discharge ports for forming flying droplets and the volume V of the droplets discharged from the droplet discharge ports is 100≧ V/So.sup.3/2 ≧0.1. Also, in a liquid injection recording apparatus, the relation that 0.1.S.sub.H ≦So.sup.3/2 ≦100.S.sub.H is satisfied between the numerical value of the minimum cross-sectional area So of a discharge orifice for forming flying droplets and the numerical value of the heater area S.sub.H of an electro-heat converting member for providing energy for causing liquid to be discharged from the discharge orifice.
