Abstract: An ink jet recording method performs recording on a recording medium using a white ink composition, a non-white ink composition, and a treatment liquid containing an aggregating agent, the method including: a treatment liquid adhesion step of adhering the treatment liquid to the recording medium to form a treatment liquid layer; a non-white ink adhesion step of adhering the non-white ink composition to the recording medium by ejection thereof from an ink jet head to form a non-white ink layer; and a white ink adhesion step of adhering the white ink composition to the recording medium by ejection thereof from an ink jet head to form a white ink layer. The recording medium has a region in which the non-white ink layer, the white ink layer, and the treatment liquid layer are overlapped with each other, at least one of the ink compositions contains resin particles and a water-soluble resin, and the water-soluble resin has a glass transition temperature higher than that of a resin of the resin particles.
