The image recording method includes a first process of applying a first black ink containing a pigment to a record medium; and, after the first process, a second process of applying a second black ink containing a pigment to the record medium such that the second ink at least partly overlaps the first black ink, in which the first black ink contains a salt containing at least one kind of cation selected from the group consisting of an alkali metal ion, an ammonium ion, and an organic ammonium ion and at least one kind of anion, and the static surface tension of the first black ink is higher than the static surface tension of the second black ink. |

1. An image recording method, comprising:
a first step of applying a first black ink containing a pigment to a record medium; and after the first step, a second step of applying a second black ink containing a pigment to the record medium such that the second ink at least partly overlaps the first black ink, whereinthe first black ink contains a salt containing at least one kind of cation selected from the group consisting of an alkali metal ion, an ammonium ion, and an organic ammonium ion and at least one kind of anion selected from the group consisting of Cl−, Br−, I−, ClO−, ClO2−, ClO3−, ClO4−, NO2−, NO3−, SO42−, CO32−, HCO3−, HCOO−, (COO−)2, COOH(COO−), CH3COO−, C2H4(COO−)2, C6H5COO−, C6H4(COO−)2, PO43−, HPO42−, and H2PO4−, anda static surface tension of the first black ink is higher than a static surface tension of the second black ink. |
