摘要： Four color toners of yellow, magenta, cyan and black, and four two-component developers containing the four color toners respectively in combination with a resin-coated ferrite carrier suitable for multi-color electrophotographic copying are provided. Each of the four-color toners is strictly regulated in relation not only to the carrier but also to the other color toners. More specifically, each color toner is strictly controlled with respect to a particle size distribution, freeness from agglomeration, melting characteristics including heat-absorption peaks and apparent viscosity on melting, chromaticity, triboelectric chargeability and optical toner concentration detection characteristic. Because of the strict regulation of these various parameters, the resultant multi-color toner or developer system shows excellent performances at every stage of multi-color electrophotography including development, transfer and fixing (color-mixing) for a long period of successive copying.

摘要： A negative latent image is formed on a photosensitive member comprising an organic photoconductive material. The negative latent image is developed with a positively chargeable developer containing positively chargeable fine silica particles adapted to the organic photosensitive member. The developed image is transferred to a transfer material and the residual toner on the photosensitive member is removed. Thus, copied images without fog can be obtained successively.
