There is provided an image forming apparatus including: a sensitivity calculating unit; a first correction amount calculating unit that calculates, for each of the different density values of the color material, correction amounts for correcting density nonuniformity with respect to each recording element in regard to each of the color signals on the basis of reading data; and a second correction amount calculating unit that calculates, for each of the different density values of the color material, correction amounts of the density values of the color material on the basis of the correction amounts of the color signals for each of the different density values of the color material, with respect to the recording elements, and on the basis of the sensitivities of each of the color signals in regard to each recording element.
