An ink-jet printing method for obtaining higher quality printed Images by utilizing an ink-jet recording technology using a pigment ink and a treatment liquid. A treatment liquid for unstabilizing the dispersed condition of the pigment in the aqueous medium is applied onto the printing medium, and subsequently either an ink containing a self-dispersion type pigment and a pigment dispersed by a polymeric dispersant or an ink containing a self-dispersion type pigment and an ink containing a pigment dispersed by a polymeric dispersant are applied together to the printing medium in such a way that the treatment liquid and the inks are mixed in a liquid state on the printing medium to make the pigments indissoluble.
