An ink set including at least 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-S4≦1.2 mass %, and S3 and S4 are each 0.1 mass % or more.
