Aqueous ink, ink cartridge, and ink jet recording method

An aqueous ink for ink jet comprising:

• a pigment;
• a water-soluble resin for dispersing the pigment;
• a water-soluble organic solvent having a dielectric constant at 25° C. of 20.0 or more to 30.0 or less;
• an acetylene glycol type surfactant;
• and
• a fluorinated surfactant,
• wherein the acetylene glycol type surfactant comprises an acetylene glycol ethylene oxide adduct having an HLB value determined by Griffin's method of 10 or more,
• wherein the fluorinated surfactant comprises a perfluoroalkyl ethylene oxide adduct having a perfluoroalkyl group with six or less carbon atoms,
• wherein a content (% by mass) of the fluorinated surfactant in the ink is 0.01% by mass or more to 0.08% by mass or less based on the total mass of the ink,
• wherein a content (% by mass) of the water-soluble organic solvent relative to a content (% by mass) of the fluorinated surfactant based on the total mass of the ink is 100 times or more to 200 times or less in terms of mass ratio, and
• wherein the aqueous ink has a dynamic surface tension γ10 at a lifetime of 10 ms of 40 mN/m or less and a static surface tension γ of 25 mN/m or more.
