Described herein is an invention that relates to chemiluminescence-directed antiviral activities of natural and synthesized light-sensitive compounds. In some embodiments, the allowing telephone calls comprises calling a programmed caller number and calling to a called party number associated with the e-mail address. The print head includes a heater chip having heating elements, each of which is associated with a corresponding one of the nozzles. A spray liquid containing the electrode catalyst and a solvent is applied onto a surface of the membrane 2 by electrostatic spray deposition to selectively adhere the electrode catalyst 5 on the surface sites of the membrane 2 which corresponds to the ion-conductive domains 3. The pre-discharge is performed immediately before recording per line, and the number of discharges is set to be larger for the electrothermal converting element on the side away from the discharge port than the number of discharges for the electrothermal converting element on the side near to the discharge port.
