Abstract:
A method and an apparatus for supplying and injecting liquid droplets are provided to avoid a thermally abnormal phenomenon by forming the liquid droplets in a space and performing injection from a nozzle by a static electricity effect. An apparatus for supplying and injecting liquid droplets includes a liquid droplet forming section(200) and a nozzle(300). The liquid droplet forming section separates liquid droplets(100) from a supplied ink to form the liquid droplets. The nozzle sprays the liquid droplets from the liquid droplet forming section. In the liquid drop forming section, an electrode is disposed along the movement direction of the droplets and an insulation body is disposed on the electrode.
