<P>PROBLEM TO BE SOLVED: To restrain a pigment on a recording surface of a recording medium from sticking to a discharge roller even if a time until the discharge roller comes into contact with the recording medium after the ejection of ink to the recording medium is short to achieve high speed processing by increasing the residual amount of the pigment on the recording surface of the recording medium to achieve high image quality when forming an image on ordinary paper such as PPC paper, in an inkjet recording method of sticking ink to the recording medium after sticking a treatment liquid to the recording medium. <P>SOLUTION: The treatment liquid in use contains polyvalent metal salt and an emulsion of a cationic polymer compound. An inkjet recording device 1 fills a roll coater 9 with the treatment liquid of this composition to carry out an inkjet recording method of sticking the ink containing the pigment to the recording medium X by a recording head 5 after sticking the treatment liquid containing the polyvalent metal salt and the emulsion of the cationic polymer compound, to the recording medium X by the roll coater 9 while conveying the recording medium X by a conveyor belt 6. <P>COPYRIGHT: (C)2011,JPO&INPIT |
