Claim:
An ink jet printing method for printing an image on a print medium using a print head, the ink jet printing method comprising: a step of providing (i) an ink containing a pigment for ejection through the print head, (ii) a reaction liquid containing polyvalent metal salt that acts to coagulate the pigment contained in the ink, and (iii) a coagulation inhibiting liquid, including an alkaline water solution, used to inhibit a reaction of the pigment and the reaction liquid by making the polyvalent metal salt contained in the reaction liquid insoluble in the ink; a step of applying the coagulation inhibiting liquid to an ink absorber, wherein the ink absorber receives the ink ejected outside the print medium; and a printing step of ejecting the ink and the reaction liquid toward the print medium without leaving a margin at an edge portion of the print medium after the coagulation inhibiting liquid application step.
