An aqueous ink composition contains at least one organic solvent in a proportion of 15.0% or less relative to the total mass of the ink composition and in which the content of organic solvents having a normal boiling point of more than 280.0° C. is limited to 3.0% or less of the total mass of the ink composition. The aqueous ink composition is ejected from a printing head having a circulation flow channel through which the ink composition circulates in the printing head.
