    摘要： A process for the preparation of encapsulated toners which comprises blending core momomer or monomers, free radical initiator, pigment, and an oil soluble shell monomer; dispersing the resulting mixture in a stabilized aqueous suspension; thereafter subjecting the stabilized droplets to a shell forming interfacial polycondensation reaction by adding a water soluble shell monomer or monomers; subsequently forming the core resin binder by heat induced free radical polymerization within the newly formed capsules; washing the toner suspension; subsequently removing water therefrom in a fluidized bed dryer to obtain a dry encapsulated toner with a surface moisture content of about 0.3 percent by weight to about 0.8 percent by weight; and thereafter blending the encapsulated toner with surface additives.

    摘要： A method for making conductive toner particles includes (A) heat treating in fluidized bed processing equipment a mixture of non-conductive toner particles containing a thermoplastic resin and a colorant, and an effective amount of conductive powder blended with and coated on surfaces of the non-conductive toner particles, wherein the heat treatment is carried out at a temperature at or above the glass transition temperature of the resin for a period of time at least sufficient to fuse the conductive powder onto the surfaces of the non-conductive toner particles, and then (B) cooling the heated conductive toner particles to a temperature below the glass transition temperature of the resin. The final toner particles have a conductivity of at least about 10.sup.-8 ohm.sup.-1 -cm.sup.-1 and preferably from about 10.sup.-4 to about 10.sup.-8 ohm.sup.-1 -cm.sup.-1.
