An inkjet ink is provided, which includes a pigment dispersion containing an organic dispersant, a black pigment having an average particle diameter of not more than 200 nm, and a resinous dispersing agent, the organic dispersant being formed of at least one polymerizable compound, and the black pigment being included therein at an amount ranging from 2 to 30% by weight based on the organic dispersant, and an ionic compound. A zeta-potential of the black pigment to the at least one polymerizable compound of the organic dispersant is confined within the range of -10 mV to +100 mV.
