The inkjet recording ink contains an anionic self-dispersion pigment having an anionic functional group, a salt, and a water-soluble compound having a hydrophilicity/hydrophobicity coefficient of 0.26 or more. The ink contains a larger amount of cesium ion than the amount of the anionic functional group. The hydrophilicity/hydrophobicity coefficient is defined by equation (A).
