This inkjet image formation method has: a precoat liquid application step in which a precoat liquid is applied to a film substrate, the precoat liquid including a curing agent, a resin having a function group that reacts with the curing agent, and water; a precoat liquid drying step in which the precoat liquid applied to the film substrate is dried to form a precoat layer; an ink application step in which an ink is applied to the precoat layer by an inkjet method, the ink containing at least a coloring material, an organic solvent, and water; and an ink drying step in which the ink applied to the precoat layer is dried to form an image. The drying temperature T1, which is the highest temperature during the precoat liquid drying step, and the drying temperature T2, which is the highest temperature during the ink drying step, satisfy T2>T1.
