The copolymer or the salt thereof has at least a structural unit represented by Formula 1, a structural unit represented by Formula 2, and a structural unit represented by Formula 3 or 4. In Formula 1, R1 represents a methyl group or a hydrogen atom, M+s each represent a hydrogen ion, an alkali metal ion, or an organic ammonium ion, and m and n each, independently represent 0 or an integer of from 1 to 6 excluding a case of both m and n being 0 at the same time. In Formula 2, R2 represents a methyl group or a hydrogen atom. In Formula 3, R3 represents a methyl group or a hydrogen atom.
