PROBLEM TO BE SOLVED: To provide an ink jet ink set excellent in image quality, reliability and fixability, an ink jet recording method and an ink jet recording apparatus using the ink set. SOLUTION: At least a black ink containing at least a pigment that can be self-dispersed in water, a water-soluble organic solvent, and water, a pigment, a polymer dispersant, a water-soluble organic solvent, and water. And an ink jet ink set satisfying the following (1) to (3), and an ink jet recording method and an ink jet recording apparatus using the ink set. (1) The surface tension of the black ink and the color ink is 25 to 39 mN / m. (2) The viscosity of the black ink and the color ink at 23 ° C. is 2.0 to 10.0 mPas. (3) The average SP value of the mixed solution of the water-soluble organic solvent and water contained in the black ink is smaller than the average SP value of the mixed solution of the water-soluble organic solvent and water contained in the color ink, and , The difference is 0.01-1.5 [Selection figure] None |
