Provided are an aqueous pigment dispersion that includes an azo pigment represented by Formula (1) as described in the specification, and/or a tautomer thereof, the azo pigment showing characteristic X-ray diffraction peaks at least at Bragg's angles (2θ±0.2°) of 4.8°, 7.2°, 9.7°, 20.0°, 17.3°, 26.0°, and 26.7° in CuKα characteristic X-ray diffraction; a first dispersant; a second dispersant; and water, the aqueous pigment dispersion being obtained via the following Step b. n Step b: a step of dispersing an azo pigment represented by Formula (1) and/or a tautomer thereof, a first dispersant, and a second dispersant in water and thereby obtaining an aqueous pigment dispersion. |
