Abstract
To record a monochromatic image and a color image with a suitable amount of ink, the ink jet apparatus sets an ejecting frequency of ink droplets in printing the monochromatic image with one recording head to be double an ejecting frequency in printing the color image with plural recording heads. Alternatively, scanning speed of recording heads in printing the color image with plural recording heads is set to be double the speed in printing the monochromatic image with one recording head. This assures that the maximum number of the ink droplets ejected within one pixel of the recording medium from recording heads in printing the monochromatic image is equal to the maximum number in printing the color image.
