To provide an inkjet recording method having an image of high fastness, and an image of high precision without dot exudation regardless of light absorbing characteristics of an ink.SOLUTION: An inkjet recording method includes processes of applying an ink containing a polymerizable compound, a polymerization initiator, a solvent, and a coloring material to a recording medium, and irradiating the ink with ultraviolet rays to cure, where the ink includes a black ink containing a coloring material which forms black color by one kind, and a plurality of color inks respectively containing coloring materials capable of forming black color by subtractive color mixing, a first black dot formed by the black ink, and a second black dot formed by a plurality of the color inks contact by at least one part, and the black ink, and a plurality of the color inks are applied to the recording medium so that centers of both dots are out of alignment.SELECTED DRAWING: Figure 4 【課題】インクの光吸収特性によらず、堅牢性の高い画像とドット滲みのない高精細な画像を有するインクジェット記録方法を提供する。【解決手段】重合性化合物、重合性開始剤、溶剤及び色材を含むインクを記録媒体に付与し、前記インクに紫外線を照射して硬化させる工程を有するインクジェット記録方法で、インクは、1種でブラック色を形成する色材を含むブラックインク、及び減法混色によりブラック色を形成可能な色材をそれぞれ含む複数のカラーインクを含み、ブラックインクにより形成される第１ブラックドットと、複数のカラーインクにより形成される第２ブラックドットが少なくとも一部で接しており、両ドットの中心がずれるようにブラックインク及び複数のカラーインクを記録媒体に付与するインクジェット記録方法。【選択図】 図４
