Provided is an ink set that comprises at least four colored inks, that is unlikely to cause bleeding or mottling even when used to record on a recording material having low ink absorption ability, and that yields a recorded image having high print density. The ink set comprises at least four colored inks that include a yellow ink, a magenta ink, a cyan ink, and a black ink and that each contain water, a surfactant, and a colorant. When each of the surfactant contents in each of the total masses of the yellow ink, the magenta ink, the cyan ink, and the black ink is represented respectively by S1, S2, S3, and S4, S1 satisfies 1.0 mass% ‰¤ S1 ‰¤ 2.5 mass%, S1 - S2 satisfies 0.1 mass% ‰¤ S1 - S2 ‰¤ 0.8 mass%, S3 - S2 satisfies 0.0 mass% ‰¤ S3 - S2 ‰¤ 0.5 mass%, S3 - S4 satisfies 0.2 mass% ‰¤ S3 - S2 ‰¤ 1.2 mass%, and S3 and S4 are each 0.1 mass% or more. |
