Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount.
