The soluble organic solvent contains a compound represented by the following general formula 1 which accounts for 10-36% by mass of the total amount of ink. When the amount of the compound is equal to the amount of the solvent, the total amount of the solvent is the compound. The sum of the amounts of the color material, the water, and the water-soluble organic solvent is 100% by mass or less of the ink.
