PROBLEM TO BE SOLVED: To solve the problem that the use of a color ink having a high permeation speed with respect to a paper and a black ink having a comparatively low permeation speed are used, when a full color image causes the black ink flows into the image of the color inks to create bleeding with a marked deterioration in printing quality. SOLUTION: This inkjet recorder ejects inks having different colors from ejection nozzle faces each being provided to two or more different faces of a recording head. A conveyance passage of a recording medium placed in a printing region of the ejection nozzles is made to be longer than conventional, and then a time interval between time points of deposition of inks having different colors, particularly the black ink and the color ink on the recording medium is extended, so that the bleeding is suppressed.
