Summary:To provide a method for forming an inkjet image, which enables reliable transferability and high fastness properties of a final image.SOLUTION: An inkjet image forming method includes: an ink application step of applying an active energy ray-curable ink which contains a coloring material onto a transfer body to form a first intermediate image; a first active energy ray irradiation step of irradiating the ink applied onto the transfer body with an active energy ray to form a second intermediate image; a liquid composition application step of applying an active energy ray-curable liquid composition which does not contain the coloring material onto a part of the second intermediate image to form a third intermediate image; and a second active energy ray irradiation step of irradiating the third intermediate image with an active energy ray to form a fourth intermediate image. A complex elastic modulus (Pa) of a cured product at the time when the liquid composition contained in the third intermediate image has been temporarily cured in the second active energy ray irradiation step is 5.0 or larger and 7.1 or smaller in terms of common logarithm.SELECTED DRAWING: Figure 1 【課題】確実な転写性及び最終画像の高い堅牢性を可能とするインクジェット画像形成方法の提供である。【解決手段】転写体上に色材を含む活性エネルギー線硬化性のインクを付与して第一の中間画像を形成するインク付与工程と、転写体上に付与されたインクに対して活性エネルギー線照射を行い、第二の中間画像を形成する第一の活性エネルギー線照射工程と、第二の中間画像上の一部に対し、色材を含まない活性エネルギー線硬化性の液体組成物を付与して第三の中間画像を形成する液体組成物付与工程と、第三の中間画像に対して活性エネルギー線照射を行い、第四の中間画像を形成する第二の活性エネルギー線照射工程と、を有し、第二の活性エネルギー線照射工程において、第三の中間画像に含まれる液体組成物を仮硬化させた際の硬化物の複素弾性率（Ｐａ）が、常用対数で５．０以上７．１以下であることを特徴とするインクジェット画像形成方法に関する。【選択図】図１
