Abstract:
Provided is an ink containing a self-dispersible pigment, an acrylic resin particle, a surfactant, a water-soluble organic solvent, and water. The surfactant includes a fluorinated surfactant represented by Formula (1) and having an HLB value determined by a Griffin method of 11 or less. The water-soluble organic solvent includes at least one water-soluble organic solvent selected from a specific group, and the total content of the water-soluble organic solvents of the specific group is 4 times or more the total content of the water-soluble organic solvents other than the solvents of the specific group. The total content of the self-dispersible pigment and the acrylic resin particle is 10% by mass or less based on the total mass of the ink.
