Abstract
An inkjet ink includes: a pigment; a first surfactant; a second surfactant; and an aqueous medium. The first surfactant is a compound represented by the following general formula (I). The second surfactant is a compound represented by the following general formula (II). The aqueous medium includes water and a specific organic solvent. An octanol/water partition coefficient Log Kow of the specific organic solvent is −1.80 or more and −1.00 or less. A content ratio of the first surfactant is 0.03 mass % or more and 0.35 mass % or less. A content ratio of the second surfactant is 0.03 mass % or more and 0.30 mass % or less.
