Zusammenfassung:	To provide an ink jet recording method capable of recording an image with excellent uniformity without degrading the storage stability of the ink when recording an image using ink and a reaction liquid.SOLUTION: There is provided an ink jet recording method for recording an image by imparting a reaction liquid containing an aqueous ink and a reaction agent reacting with the aqueous ink to a recording medium. The aqueous ink contains a pigment, a first resin and a second resin, the first resin is a water-soluble block copolymer having no ethylene oxide group, the second resin is a water-soluble random copolymer and the cohesiveness of the first resin is lower than that of the second resin.SELECTED DRAWING: None 【課題】インク及び反応液を用いて画像を記録する場合に、インクの保存安定性を低下させることなく、均一性に優れた画像を記録することが可能なインクジェット記録方法を提供する。【解決手段】水性インク及び水性インクと反応する反応剤を含有する反応液を記録媒体に付与して画像を記録するインクジェット記録方法である。水性インクが、顔料、第１の樹脂、及び第２の樹脂を含有し、第１の樹脂が、エチレンオキサイド基を有しない水溶性のブロック共重合体であり、第２の樹脂が、水溶性のランダム共重合体であり、第１の樹脂の凝集性が、第２の樹脂の凝集性よりも低い。【選択図】なし
