1. An inkjet recording method comprising:
imparting a pre-processing fluid to a coated layer provided on at least one surface of a substrate of a recording medium; drying the pre-processing fluid; and forming an image on the recording medium by ejecting an aqueous ink thereon, wherein the pre-processing fluid comprises 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, where R1 and R2 each, independently represent triaryl amine groups or diethylamine groups, and n represents an integer of from 4 to 40,
R—O—(CH2CH2O)x-(CH2C(CH3)CH2O)y-H (2)Chemical formula 2 where x represents 0 or an integer of from 1 to 5, y represents an integer of from 10 to 15, and R represents CmH2m+1, where m represents an integer of from 1 to 20, 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 where n represents an integer of from 1 to 40,
CnF2n+1—CH2CH(OH)CH2—O—(CH2CH2O)a—Y (4)Chemical formula 4 where Y represents CnF2n+1 or CH2CH(OH)CH2—CnF2n+1, n represents an integer of from 4 to 6, and a represents an integer of from 4 to 14. |
