Abstract:
An ink jet apparatus, comprising:a storing section for storing an electrically conductive ink containing an electrically conductive liquid and an electrically conductive material having an electrical conductivity higher than that of the conductive liquid, said conductive material comprising a plurality of conductive particles having at least conductive surfaces with electrical conductivity to generate heat thereat;electrode means located in the storing section for applying an alternating current to said conductive ink stored in the storing section, said conductive particles in said conductive ink allowing the alternating current to flow therethrough and generating heat thereat for forming bubbles in the conductive liquid by a skin effect caused by application of said alternating current; anda nozzle attached to the storing section for ejecting the conductive ink due to generation of said bubbles by application of the alternating current.
