摘要：
To provide an ink, which contains: water; a pigment; and a first water-soluble organic solvent, wherein the first water-soluble organic solvent contains a water-soluble organic solvent (G) having a boiling point of 280° C. to 300° C., a water-soluble organic solvent (X) having a boiling point of 180° C. to 190° C., and a water-soluble organic solvent (Y) having a boiling point of 190° C. to 200° C., wherein the first water-soluble organic solvent contains a water-soluble organic solvent (G) having a boiling point of 280° C. to 300° C., a water-soluble organic solvent (X) having a boiling point of 180° C. to 190° C., and a water-soluble organic solvent (Y) having a boiling point of 190° C. to 200° C., wherein the ink satisfies the following formulae: 24≦X≦40 2≦X/Y≦20 where X [% by mass] is an amount of the water-soluble organic solvent (X), and Y [% by mass] is an amount of the water-soluble organic solvent (Y).
