<P>PROBLEM TO BE SOLVED: To provide an inkjet printer which can reduce a banding phenomenon generated in an image recorded on a recording medium by adding other two or more color inks to the domain printed with a black ink monochrome using an inkjet head having a usual structure which does not need to arrange multiple lines of nozzles of the same color in the direction perpendicular to the width direction of a sheet. Ž<P>SOLUTION: When reducing the banding in a main processing, image data is memorized (S8), and the black color density of black pixel of the memorized image data is converted (S9), then the converted image data is printed on the recording medium (S11). Accordingly, the banding phenomenon generated in the image recorded on the recording paper can be reduced. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
