PROBLEM TO BE SOLVED: To provide an image processing method for executing processing to an image wherein a plurality of regions coexist, an image processor, an image forming apparatus and a computer program. SOLUTION: Region separating processing is performed for input image data (S11), and an input image is separated into a character region, the shadow region of shadowed characters and the other region. Then, whether or not the block of a judgement object is the character region is judged (S12), and in the case of judging that it is not the character region (S12:NO), dither processing of 7×7 is executed (S13). Also, in the case of judging that it is the character region (S12:YES), whether or not the character region is the shadow region of the shadowed characters is judged (S14), the dither processing of 1×1 is executed (S15) in the case that it is not the shadow region (S14:NO), and the dither processing of 5×5 is executed (S16) in the case that it is the shadow region (S14:YES).
