Liquid jet recording method

Abstract

A liquid jet recording method capable of recording gradation comprises (a) filling with a liquid a conduit having, at the end, an orifice for ejecting and projecting a liquid droplet to a predetermined direction, said conduit being provided with a heat actuating portion generating a force for ejecting the liquid droplet by applying heat energy to the liquid to cause an abrupt state change, the heat actuating portion including an electrothermal transducer having a heat generating portion which has such a structure that the degree of heat supply is different from position to position on the heating surface, and (b) controlling the strength of an input electric signal corresponding to the gradation of an image to be recorded, thereby controlling the distribution of degree of heat supplying at the heating surface.
