Abstract
“Energy per unit volume” P2(Pa) generated in ink 4 in a second ink tank 14 is maintained to the condition “P2={(1+r)×Pn}−(r×P1)” based on “energy per unit volume” P1(Pa) generated in ink 4 in the first ink tank 12, a proportion of “1:r” between channel resistance R1 (Pa·sec/m3) of ink from the first ink tank 12 to the neighborhood of a nozzle 1 and channel resistance R2 (Pa·sec/m3) of ink from the neighborhood of the nozzle 1 to the second ink tank 14, and appropriate pressure Pn (Pa) of the ink 4 in the neighborhood of the nozzle 1.
