Abstract: An electro-thermal transducer is composed of a substrate, a resistive heater element formed on the substrate, and electrically conductive members to supply electric power to the resistive heater element, wherein the resistive heater element contains a metal boride as the principal constituent. The transducer of this construction is capable of selecting its resistivity to a high value and causing a large electric current to flow in the form of short pulses for the purpose of high speed printing, hence it is stable against repetitive pulse applications over a long period of time. The method of producing the transducer is by forming a layer of a resistive heater element including a metal boride on a substrate of an electrically insulative material by conducting a reactive sputtering reaction between a target of an elemental form of the metal and diborane gas; and then applying to the resistive heater element an electrically conductive member for supplying the resistive heater element with electric power.

Abstract: The present invention discloses a technique of effecting recording on a recording medium by a plurality of recording elements, wherein recording density by the plurality of recording elements is varied. Further, the recording density by the plurality of recording elements is varied in accordance with a time required for electrical transmission of informations to be recorded for definite numbers of scanning lines. For example, when the time required for such electrical transmission is short, the recording is effected by small numbers of the recording elements, while, when the time required for the electrical transmission is long, the recording operation is effected by large numbers of the recording elements, thereby preventing the image quality from lowering.
