ABSTRACT:
An air babble trapping apparatus which traps an air bubble in ink includes: a filter having through holes formed in the substrate and an insulating layer with a low wettability formed in a surface of the substrate; and an electric potential control unit which controls an electric potential difference between the electroconductive substrate and the ink. When the electric potential difference is set to be zero, the air bubble in the ink is adhered to a surface of the filter because of the low wettability of the insulating layer. When the electric potential difference is set to be a predetermined value, the air bubble adhered to the surface of the filter is released since the wettability of the surface of the insulating layer of the filter is increased due to an electrowetting phenomenon.
