PROBLEM TO BE SOLVED: To provide the forming method of colored part on a material to be recorded and an ink jet recording device, which are wide in a color reproducing area, excellent in the uniformity of color, restraining the bleeding of the boundary part of colors effectively, in which different color areas are neighbored on the material to be recorded, and prominent in scratching property, as well as an ink set, prominent in ink jet recording characteristics such as preservation stability, discharging stability of a recording head and the like. SOLUTION: The ink set is provided independently with aqueous ink, having an anionic property including coloring materials or cationic property, and a liquid composite, containing fine particles whose surfaces are charged in a polarity opposite to the ink. In the ink set, the forming method of a colored part on a medium to be recorded and the ink jet recording device, the pH value of the mixed solution when the ink and the liquid composite are mixed with the weight ratio of substantially 1 to 1 is adjusted so as to be the pH value wherein at least the flocculation of the coloring materials is caused. |
