PROBLEM TO BE SOLVED: To provide an image-forming apparatus which makes a color shift of a total image look less conspicuous and forms good-quality images with gradation features of a monochromatic image area, particularly, a photographic part improved. SOLUTION: A monochromatic photographic area and a full-color photographic area are distinguished when an original is read. Gradation features are emphasized for the full-color photographic area. Therefore, a color shift is taken into consideration although a number of image formation lines is small, and images are formed so that the direction of the image formation lines becomes parallel to a rotation direction of a photosensitive drum (b). On the other hand, the count of image formation lines is reduced at the monochromatic image area to enhance the gradation features more, and images are formed so that the image formation line holds a constant angle to the rotation direction of the photosensitive drum (a). |
