Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink set capable of improving an image density and scratch resistance in a recorded image using an ink containing a self-dispersion pigment and an ink containing a modified siloxane compound. SOLUTION: The ink set for inkjet recording is composed of a plurality of inks comprising a first ink and a second ink independently, the first ink containing at least a pigment having functional groups on the surface of pigment particles, and a compound having adsorptivity to the pigment wherein the functional group density on the surface of the pigment particles is 1.5 μmol/m2or more and less than 2.6 μmol/m2, the second ink containing at least a pigment and a modified siloxane compound.
