Abstract: According to one embodiment, an aqueous inkjet ink includes a color material, water in an amount of 50-70% by mass of the total amount of the ink, and a water-soluble organic solvent in an amount of 29-49% by mass of the total amount. 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. Where, X1, X2, and X3 each independently represent EOn, and X4 represents an CH3CH2— or an (EOn)O—. EOn is represented by the following general formula 2, where n representing an integer of 1-5. CH2—CH2nOH  general formula 2
