Abstract
A novel magenta developer system is provided which employs a 2,9-dimethylquinacridone pigment and a resin toner in combination with a carrier coated with resin containing copper tetra-4-(octadecylsulfonomido) phthalocyanine. Thus, a magenta developer is provided for the first time which is capable of employing a coated conventional carrier, thereby simplifying the color electrophotographic process. Color electrophotographic process employing this developer are also disclosed.
Claims14
An electrostatographic developer for developing electrostatic latent images comprising toner particles and coated carrier particles, said toner comprising a resin material and a 2,9-dimethyl-quinacridone colorant, said coated carrier comprising carrier material particles overcoated with a composition comprising a resin and copper tetra-4-(octadecylsulfonomido) phthalocyanine colorant.
An electrostatographic imaging process comprising establishing an electrostatic latent image on a surface and contacting said surface with an electrostatographic developer comprising toner particles and coated carrier particles, said toner particles comprising a resin and a 2,9-dimethylquinacridone colorant and said coated carrier comprises carrier material particles overcoated with a composition containing a resin a copper tetra-4-(octadecylsulfonomido) phthalocyanine colorant to develope said latent image.
