Abstract: An ink jet recording ink including a coloring material; water; and three kinds of water-soluble compounds. The content of the water is 70 mass % or more with respect to the total amount of the ink. Each water-soluble compound has a molecular weight of 80 or more and is a liquid compound having a vapor pressure at 20° C. of 5 Pa or less or a solid compound, and at least one kind of the water-soluble compounds is a solid compound. In case that the water-soluble compounds are mixed at a ratio at which the water-soluble compounds are incorporated into the ink to provide a mixture, a 40% aqueous solution of the mixture has a water activity value of 0.88-0.91 and a viscosity of 3.3 mPa·s or less. The total content of the water-soluble compounds in the ink is 20-25 mass % with respect to the total amount of the ink.
