ABSTRACT:
An image forming apparatus, for forming an image by using distribution of plural types of dots, including: a first section, for making comparison between a pixel value of a target pixel and a value in a dither matrix stored in advance, and determining, whether a dot having the highest density be formed at a position corresponding to the pixel; a second section for determining whether a second type dot having lower density be formed at the position where the dot having the highest density is determined not to be formed; and a section for instructing, based on results of determination by the first and second sections, whether a dot should be formed at the position, wherein the dither matrix comprises values, each being not less than a predetermined value smaller than the maximum pixel value of the input image.
