<P>PROBLEM TO BE SOLVED: To provide an inkjet image forming method in which both of an initial film-forming capacity having superior weatherability, forming high gloss and high coloring images and contributing to ozone gas resistance and glossiness without impairing ink absorbency, and film destruction suppression in reserving the images for a long time under conditions of high temperature and high humidity, are compatible with each other. <P>SOLUTION: In the inkjet image forming method for ejecting an ink composition onto an inkjet recording medium, the inkjet recording medium is a void type inkjet recording medium having a porous ink absorbing layer, an inkjet head has nozzles ejecting two or more types of ink compositions, at least one type of the ink composition is a colorless ink containing no coloring agent, at least one type of the ink composition is a color ink containing a coloring agent, the colorless ink contains one or more mass% of resin particles having an average particle diameter of 10 to 200 nm, and the ink composition has a pH of 6.5 to 11.0, with a difference from the film surface pH of the inkjet recording medium being less than 4.0. <P>COPYRIGHT: (C)2007,JPO&INPIT |
