Abstract: A method for manufacturing an aqueous black pigment dispersion, including the steps of subjecting a mixture containing carbon black and an aqueous medium to media-less dispersion and adding a resin having anionic groups and a basic compound after the dispersion, wherein the carbon black has a carboxylic acid group on the surface such that the value produced by dividing the amount of carboxylic acid group present on the surface by BET value is 0.8 to 5.5 (μmol/m2) and the resin having anionic groups is an urethane resin that satisfies (weight average molecular weight/acid value)
