An inkjet ink containing at least a pigment, a water-soluble solvent, at least two types of surfactant, and water, wherein: (I) at least one type of nonionic surfactant, and at least one of an anionic surfactant and/or an amphoteric surfactant are contained as the surfactants; (II) the nonionic surfactant has a weight-average molecular weight of 1000 or less and an SP value of 9.2 to 13, and the total number of carbon atoms and oxygen atoms in a unit constituting a hydrophilic group portion is 10 or more in the nonionic surfactant; and (III) the at least one of an anionic surfactant and/or an amphoteric surfactant has a weight-average molecular weight of from 175 to 1500. |
