IMAGE-FORMING DEVICE AND COLOR IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image-forming device which enlarges the color- reproducing range and enhances sharpness of image quality, using deep toner and pale toner. SOLUTION: When deep toner stuck mainly on a latent image part of high density has a charge quantity QH and a weight average grain sizeθH and pale toner stuck mainly on the latent image part of a low density has charge quantity QL and a weight average grain sizeθL, relations QH>QL andϕH<ϕL are satisfied.
