The image processing device executes first correction process and second correction process. The first correction process comprises correcting a pixel value corresponding to a first partial area, which is included in the achromatic-color representation area and is adjacent to the chromatic-color representation area, such that the achromatic color ink in the first partial area decreases to be zero, at least one of the three or more types of chromatic color inks increases, and the pixel value represents the achromatic color. The second correction process comprises correcting a pixel value corresponding to a second partial area, which is included in the achromatic-color representation area and is adjacent to the first partial area and is remote from the chromatic-color representation area, such that the achromatic color ink in the second partial area decreases to a specific value more than zero, at least one of the three or more types of chromatic color inks increases, and the pixel value represents the achromatic color.
