An image processor comprises means for determining generation of a dot by a dither method when an inputted data is a low gray level region not larger than a first threshold, means for generating a dot and distributing an error in a peripheral area when the inputted data is in a high gray level region larger than a second threshold, and means for generating a dot and distributing an error in a peripheral area when the inputted data is in a region higher than an intermediate gray level region larger than the first threshold and not larger than the second threshold, and for generating no dot and distributing an error the portion by which the inputted data exceeds the first threshold in a peripheral area as error, so that different tone level processing is performed in accordance with the gray level of the inputted data.
