To provide a recording method which is good in discharge stability of an ink composition and can obtain a recorded matter having excellent metallic gloss.SOLUTION: There is provided a recording method which comprises: an adhering step of adhering an ink composition to a recording medium by discharging the ink composition from an inkjet head; and a first heating step of heating the recording medium in the adhering step, wherein the adhering step has a step in which the discharge frequency of the ink composition is 15 kHz or more, the ink composition comprising a metallic pigment and a solvent component, the solvent component containing an organic solvent, the metallic pigment being scaly and metal particles, the surface of which is treated with a compound represented by the following formula (1) or the following formula (2). (R1-)P(O)(OH)2...(1), and (R2-O-)aP(O)(OH)3-a...(2), wherein, R1 and R2 each independently represent a hydrocarbon group having 14 or more carbon atoms which may be substituted with a substituent, and a represents 1 or 2.SELECTED DRAWING: None 【課題】インク組成物の吐出安定性が良好で、金属光沢に優れた記録物を得ることができる記録方法を提供する。【解決手段】インク組成物をインクジェットヘッドから吐出して記録媒体に付着させる付着工程と、前記付着工程において、前記記録媒体を加熱する一次加熱工程と、を備え、前記付着工程は、前記インク組成物の吐出周波数が１５ｋＨｚ以上の工程を有し、前記インク組成物は、金属顔料と、溶媒成分と、を含有し、前記溶媒成分は、有機溶剤を含み、前記金属顔料は、鱗片状であって、下記式（１）又は下記式（２）で表される化合物により表面が処理された金属粒子である、記録方法。（Ｒ１－）Ｐ（Ｏ）（ＯＨ）２・・・（１）（Ｒ２－Ｏ－）ａＰ（Ｏ）（ＯＨ）３－ａ・・・（２）（式中、Ｒ１、Ｒ２は独立して、置換基で置換されていてもよい炭素数１４以上の炭化水素基を表し、ａは、１又は２を表す。）【選択図】なし
