PURPOSE:To provide a high-quality image without the necessity of using a special mechanism as a temperature control device which controls the temperature of a recording medium when recording technique using a hot melt ink is employed as well as a low-priced hot melt ink recording device. CONSTITUTION:A groove is machined for a flow path 3a in a flow path plate 3, then a piezoelectric element 2 and the flow path plate 3 are formed in one piece, and a heater 16 is arranged on the flow path plate 3 of an ink jet head 20 which applies a voltage to a drive element of the piezoelectric element 2 in the selected flow path 3a and thereby ejects liquid droplets from a nozzle 6a. A head 20 is heated using a heater 16 or the heating is stopped so that the temperature of the head 20 corresponds to an ambient temperature. |
