The water-based reactive liquid contains a water-soluble high-molecular compound in a state dissolved therein. The water-based ink contains a second component, which is not insolubilized by the first component and the coloring material, in a state dissolved therein. The water-soluble high-molecular compound is not insolubilized by the first component and the coloring material but insolubilized by the second component.
