Abstract
A liquid jet recording head includes a base member, a liquid layer maintained on the base member and a plurality of heater elements, arranged in a line on the base member, for supplying energy to liquid adjacent thereto, the energy operation portions being put under the liquid layer. A method for making a liquid drop fly from the liquid jet recording head onto a recording sheet so that a dot image is formed on the recording sheet includes steps of (a) generating a bubble in the liquid to which the energy is supplied by each of energy operation portions in accordance with image data; (b) making the bubble grow up until a predetermined size of the bubble is obtained; (c) contracting the bubble under a condition where each of the energy portions supplies no energy to the liquid in which the bubble is formed; and (d) making the bubble disappear into the liquid.
