Abstract:
An inkjet recording method includes imparting a pre-processing fluid to a coated layer provided on at least one surface of the substrate of a recording medium, drying the pre-processing fluid, and forming an image on the recording medium by ejecting an aqueous ink thereon. The pre-processing fluid contains a hydrosoluble organic solvent, a flocculating agent formed of a quaternary salt of an adduct of alkyl amine.epichlorohydrine represented by the following chemical formula 1, and a nonion-based surfactant represented by the following chemical formula 2, wherein the aqueous ink comprises a colorant, a hydrosoluble organic solvent, and a fluorine-containing surfactant represented by the following chemical formula 3 or 4: C6F13—CH2CH2O(CH2CH2O)nH (3) Chemical formula 3 CnF2n+1—CH2CH(OH)CH2—O—(CH2CH2O)a—Y (4) Chemical formula 4.
