    Abstract: This invention is generally directed to electrostatographic carrier compositions comprised of a core, containing from about 0.004 weight percent to about 10 weight percent of a polymerized organoalkyoxysilane coating, wherein the monomers to be polymerized are selected from the group consisting of organoalkoxysilane monomers of the following formulas: R-Si-(OR1)3, and wherein R1 is an alkyl group containing from about 1 to about 6 carbon atoms, and R, R2, and R3, are independently selected from the group consisting of alkyl groups, substituted alkyl groups, aromatic groups, and substituted aromatic groups. Developer compositions containing such carrier particles, and including therein toner resins, as well as methods of imaging utilizing such compositions are also embraced within the present invention.

    Abstract: A magnetographic imaging member is provided which includes a photoconductive layer sandwiched between a transparent conductive substrate and an overcoating of magnetic particles dispersed in a dielectric material. A magnetic latent image is formed in the member by first producing an electrostatic latent image on the premagnetized dielectric coating and developing it with a thermal radiation reflective toner. The surface is then subjected to thermal radiation which demagnetizes the pigment in the overcoating by raising it to a temperature above its Curie point except in the areas where the developed electrostatic image reflects the heat. The latent magnetic image can be repetitively developed with magnetic toner.

    Abstract: A color electrophotographic process is provided which employs magenta, cyan and yellow toners, each in combination with a carrier coated with a resin containing copper tetra-4-(octadecylsulfonomido) phthalocyanine. Thus, for the first time a developer package is provided which is capable of producing prints of sharp quality employing a common carrier. The various magenta, cyan and yellow toners employed in connection with the newly provided coated carrier are also disclosed.

    Abstract: Reproduction process comprises producing image on an electrically conductive support having a layer of soluble organic material and developing this latent electrostatic image by immersing in a solvent for the layer, the duration of action of the solvent on the layer being so calculated that the background areas are dissolved while the image areas remain as raised areas on the support.
