An ink set includes a recording ink and a displacement ink. The recording ink contains a pigment, a resin, water, and a first surfactant and is substantially free of alkyl polyols with a normal boiling point of 280° C. or more. The displacement ink contains water, a second surfactant, an aprotic polar solvent, and an alkyl polyol with a normal boiling point of 280° C. or more. Each of the first surfactant and the second surfactant includes a silicone surfactant and/or a fluorosurfactant. The resin includes a water-soluble resin and/or a resin emulsion. The recording ink has a higher surface tension than that of the displacement ink.
