    摘要： A process for the preparation of toner comprising mixing a colorant dispersion in water, which dispersion is comprised of a colorant and an ionic surfactant with a resin latex; heating the resulting flocculent mixture with stirring at a temperature of from about 25.degree. C. to about 1.degree. C. below the glass transition temperature (Tg) of the latex resin to effect formation of toner sized aggregates; heating the resulting aggregate suspension in the presence of additional anionic surfactant, and which heating is at a temperature of from about 10.degree. C. to about 55.degree. C. above the Tg of the resin; cooling; adding a base component to the resulting slurry; filtering; and thereafter drying said toner.

    摘要： Disclosed is a marking material comprising (a) toner particles which comprise a resin and a colorant, said particles having an average particle diameter of no more than about 7 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein said toner particles are prepared by an emulsion aggregation process, and (b) hydrophobic conductive metal oxide particles situated on the toner particles. Also disclosed is a process for depositing marking material onto a substrate which comprises (a) providing a propellant to a head structure, said head structure having a channel therein, said channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through the channel to form thereby a propellant stream having kinetic energy, said channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material comprises (a) toner particles which comprise a resin and a colorant, said particles having an average particle diameter of no more than about 7 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein said toner particles are prepared by an emulsion aggregation process, and (b) hydrophobic conductive metal oxide particles situated on the toner particles.
