The ink composition contains at least one water-soluble low-molecular-weight organic compound that has a melting point of 30° C. or above and is any of an amide, sulfur-containing compound, or cyclic ether, and the low-molecular-weight organic compound constitutes 10% by mass or less of the total mass of the ink composition. The ink composition also contains at least one organic solvent that is a diol having a melting point of 25° C. or below, and the organic solvent constitutes a higher percentage than the low-molecular-weight organic compound.
