Abstract
Abstract An image forming apparatus wherein an image for a predetermined region of a recording material is formed using images having a complementary relation by a plurality of scans of a recording head, the apparatus including allocating means for allocating a multi-level image data for the predetermined region for the scans; gradation reducing means for reducing gradation of the multi-level image data allocated by the allocating means, respectively; image forming means for forming an image having the complementary relation by driving the recording head in the scans on the basis of the image data having gradations reduced by the reducing means; wherein the complementary relation of the image by the forming means is reduced by at least one of the allocating means and the gradation reducing means.
