    摘要： Provided is an ink set including at least two inks each including a coloring material, an organic solvent, and water, wherein a proportion of the organic solvent in each of the inks is 30 percent by mass or greater, wherein a relative mobility difference (maximum relative mobility−minimum relative mobility) between a maximum relative mobility and a minimum relative mobility among relative mobilities of the coloring materials included in the inks is 0.1 or greater, where the relative mobilities are obtained by thin-layer chromatography in which the coloring materials are developed using the organic solvents included in the inks as developing solvents.
