PURPOSE:To record high-quality pictures with high resolution at high speeds by a method in which the ratio of the distance between the adjacent thermal action faces to the shortest distance between the center of the thermal action faces and the center of the corresponding jet port is set up within a specific value range. CONSTITUTION:In a liquid jet recorder using a heat energy, dimensions and shape are determined such that the relations between the distance PH between the centers of the thermal action faces 107 of the adjacent electricity-heat converters 102 and the shortest distance DOH connecting the center of the thermal action faces 107 with the center of the corresponding orifice 105 meet the equation. In a liquid jet recorder designed in this way, a liquid is discharged from only the orifice 105 corresponding to the thermal action faces 107 constituting the electricity-heat converter 102 in response to a drive signal and flying liquid droplets are formed. An interference, if any, with the adjacent orifice 105 is negligible, and therefore, liquid droplets of constant sizes can be discharged toward a fixed direction with a fixed speed in response to a recording signals. |
