发明名称 METHOD OF FORMING ELECTROPHOTOGRAPH.
摘要 <p>A color electrophotographic method wherein toner images of black, yellow, Magenta and cyan are superposed on a photosensitive material (54) and transferred to a piece of paper at a time. Black is transferred by the contact developing method and colors are transferred by the DC field fly-developing method, the exposure being effected while switching the exposure quantity for black and the exposure quantity for colors. In effecting the color exposure, furthermore, the exposure quantity is increased or decreased for the high-lighted portion and for the shadow portion. By switching the exposure quantity for black and colors, there is obtained a full-color image having high chroma in which black component and color components are well-balanced. In the color image portion, furthermore, the image features excellent reproducibility for high-lighted portion and shadow portion.</p>
