An object is to provide an aqueous ink-jet ink which has satisfactory dispersibility into organic and inorganic matrices, excellent dispersibility, storage stability, and can be discharged smoothly, does not invite clogging of discharge heads even after the ink is not used for a long time, and can form images free from bleeding. An aqueous ink-jet ink contains a solvent selected from water, hydrophilic solvents, and mixtures thereof; a binder; a coloring agent; and a surfactant. The ink contains 0.5% by mass or more of a dendritic branching molecule as the binder, and/or a dendritic branching molecule including at least one of metal ions, metal particles, alloy particles, and dyes as the coloring agent.
