ABSTRACT:
The present invention provides an electrophotographing apparatus for forming a color image of an improved image quality. For the provision of such an apparatus, a plurality of color developing means are arranged in the traveling direction of the electrophotographing member. The length of the traveling direction of the photosensitive member becomes longer, and the dark attenuation characteristics are created. The resultant problems which tend to lower the image quality are solved.
In consideration of the dark attenuation characteristics of an electrophotographing photosensitive member, the present invention performs fine color adjustments according to each color of an developing image. In this adjustment, the gradation is corrected, or the color is corrected, per color in accordance with the dark attenuation characteristic.
