Zusammenfassung:	To provide a precoat liquid excellent in transferability of an image and capable of giving a high-precision image.SOLUTION: A precoat liquid of the present invention is used in an intermediate transfer type image forming method using an active ray-curable ink and an intermediate transfer body, the precoat liquid to be imparted to a surface of the intermediate transfer body before coated with the active ray-curable ink. The precoat liquid contains a water-soluble polymer, a hydrophilic liquid, a surfactant, and water, and the content of the water-soluble polymer is 0.1 pt.mass or more and 100 pts.mass or less with respect to 100 pts.mass of the hydrophilic liquid.SELECTED DRAWING: Figure 1 【課題】画像の転写性が良好であり、高精細な画像を得ることができるプレコート液を提供すること。【解決手段】本願発明のプレコート液は、活性線硬化型インクおよび中間転写体を用いる中間転写型の画像形成方法において、前記活性線硬化型インクが付与される前の前記中間転写体の表面に付与されるプレコート液である。前記プレコート液は、水溶性ポリマー、親水性液体、界面活性剤および水を含み、前記水溶性ポリマーの含有量は、前記親水性液体１００質量部に対して、０．１質量部以上１００質量部以下である。【選択図】図１
