Abstract
An ink jet recording method which comprises contacting or bringing closer an electro-thermal transducer with or to a recording liquid in an operating chamber having a discharge orifice, introducing into the electrothermal transducer an input pulse signal with its pulse width being in a range of from 0.1 .mu.sec. to 500 .mu.sec., said input pulse signal being introduced in such a manner that its input cycle becomes at least three times as large as said pulse width, discharging and sputtering said recording liquid from said discharge orifice in the form of fine droplet in accordance with operating force developed within said operating chamber, and effecting image recording on the surface of a recording medium with the liquid droplets.
