There are provided an image processing method and an image processor which realize the processing of restricting image degradations such as“dot delay”,“banding”and“wind ripple”with a simpler circuit construction. Therefore, after the regular quantization processing is performed, in a pixel in a prohibition position the processing of limiting a predetermined quantized value to change into another quantized value is performed corresponding to the obtained quantized value and the position information of the pixel of interest. By doing this, even in the low level of the density value, it is possible to realize at a low cost the construction in which dots having different sizes are mixed for printing.
