    摘要: An object of the present invention is to provide an aqueous ink which can form a more excellent image in bleeding resistance, character quality and print density than the image formed by using an aqueous ink containing a conventional self-dispersion pigment and a salt. The aqueous ink includes a self-dispersion pigment and a salt, in which the self-dispersion pigment is a pigment containing a pigment particle having a —R—(COOM1)n group bonded to a surface of the pigment particle, wherein R represents an alkylene group or an aromatic ring; M1 represents a hydrogen atom, an alkali metal, an ammonium or an organic ammonium; and n is an integer of 2 or more.
