  • Image forming apparatus and image processor
    Patent number: 6044204
    Abstract: To prevent the density of a low density part when an output image varies from the low density part to a high density part in a vertical scanning direction from being lowered without expanding an image forming apparatus or an image output device and increasing the cost, an image processing section first extracts an edge picture element of the low density part which is in contact with the high density part when an image output based upon input image data Si varies from the low density part to the high density part in the vertical scanning direction or from the high density part to the low density part in the vertical scanning direction.
