Liquid injection recording apparatus

摘要

In a liquid injection recording apparatus having discharge ports for discharging liquid and forming flying droplets, liquid flow paths communicating with the discharge ports, and energy generating means generating energy for causing the liquid to be discharged from the discharge ports, when the shortest length from the center line of the discharge ports to the central position of the energy acting surface of the energy generating means is a and the length from the center line of the discharge ports to the bottom surface of the liquid flow paths just beneath the center of the discharge ports is b, the value of a/b is 50 or less.
