Abstract
An ink containing an ethylene oxide adduct of a dihydric alcohol, having a hydrocarbon group with 9 or less carbon atoms and having an I/O ratio ranging between 1 and 1.37, is supplied via nozzles in the form of liquid droplets onto a recording paper sheet, so that fine bubble may be suppressed from being generated in the ink to prevent emission defects such as non-emission or warped emission, and hence a high quality image free of blurring or white spots may be produced.
