Provided is an ink jet recording method by which even when an ink jet recording apparatus having a small size and high durability is used, excellent sticking recoverability is obtained and a high-quality image suppressed from causing unevenness can be recorded. The ink jet recording method includes recording an image with an ink jet recording apparatus including: a plurality of aqueous inks; a first ink storage portion; a second ink storage portion; a plurality of tubes; a recording head; and a recovery mechanism. The ratio (η2/η1) of the viscosity η2 (mPa·s) of the second ink to the viscosity η1 (mPa·s) of the first ink is 0.7 or more to 1.5 or less, and the first ink contains a first water-soluble organic solvent having a specific dielectric constant of 40.0 or more.
