An aqueous ink that enables recording of an image with suppressed feathering and has high ejection stability can be provided. An aqueous ink for ink jet contains a pigment, a polyhydric alcohol derivative and a water-soluble organic solvent. The polyhydric alcohol derivative is a compound in which a proportion of {Y/(X+Y)}×100 (%) where X mole(s) of ethylene oxide group(s) and Y mole(s) of propylene oxide group(s) are added to polyhydric alcohol having three or more hydroxy groups is 55% or more to 95% or less. The water-soluble organic solvent includes a first water-soluble organic solvent having a relative dielectric constant of 10.0 or more to 40.0 or less.
