Abstract:
1. A recording liquid comprising: a coloring matter; a solvent for dissolving or dispersing the coloring matter; and a nonionic surfactant, wherein the recording liquid is contained in a liquid chamber of a liquid ejection apparatus comprising the liquid chamber for containing a liquid, a pressure-generating element which generates a pressure to press the liquid contained in the liquid chamber, and an ejection device which is provided with an ejection port for ejecting the liquid pressed by the pressure-generating element in the form of droplets, which drives the pressure-generating element with a pulsed current at a frequency of 5 kHz or more, and which ejects each droplet with a volume of 10 pl or less, the recording liquid being formed into droplets and allowed to adhere to an object so that recording is performed on the object; and wherein the recording liquid has a foaming power of 0 mm to 50 mm and a foam stability of 0 mm to 50 mm, the foaming power and the foam stability being determined by substantially the same test method as that used to determine the foaming power and foam stability according to JIS-K3362.
