Filed:

Dec 14, 2004

Appl. No.:

11/011693

Inventors:

Mark Stachowski - Fairport NY, US
Stewart Blair - Rochester NY, US

International Classification:

B02C001/00

US Classification:

241027000

Abstract:

An apparatus () for reducing the particle size of a bulk particulate or powder material includes one or more first particle-size reducing stages () and a final particle-size reducing stage (). The first particle-size reducing stage () receives the bulk material and reduces the particle size thereof to an intermediate particle size. The final particle-size reducing stage () receives the bulk material having the intermediate particle size and further reduces the particle size thereof from the intermediate particle size to a desired particle size.

Jul 9, 2004

Appl. No.:

10/888059

Inventors:

Mark Stachowski - Rochester NY, US
David Nikodem - Pittsford NY, US

International Classification:

G03G 9/087

US Classification:

430108110, 430109300, 430109400, 430109500, 430108100, 430108600, 430137200

Abstract:

A method () for forming a microtoner (C) for use in the development of electrophotographic images includes blending at least one polymer (P, P, P, . . . P) with at least one thermoplastic polymer (P, P, P, . . . P) and with one or more pigments to thereby form a dry mix toner formulation (D). The dry mix toner formulation (D) is melt mixed to thereby form a melt mix toner formulation (M) which is pulverized into an unclassified intermediate toner mix (U). At least one surface treatment addenda material (X) is dry blended with the unclassified intermediate toner mix (U) to thereby produce a surface treated unclassified toner mix (S), which is then classified to produce a surface treated classified microtoner formulation (C) having an improved particle size distribution.

Appl. No.:

10/887967

Inventors:

Mark Stachowski - Rochester NY, US
David Nikodem - Pittsford NY, US

International Classification:

D01D 5/40

US Classification:

264140000

Abstract:

A microtoner (C) and method for producing same () is presented. The microtoner (C) includes a blend of at least one polymer (P, P, . . . and P) and at least one thermoplastic polymer (P, P, . . . and P). The method () of producing microtoner (C) includes blending () the at least one polymer with the at least one thermoplastic polymer and with one or more pigments to thereby form a dry mix toner formulation (T). The toner formulation (T) is pulverized () by mechanical means into an unclassified particulate microtoner (U). The unclassified particulate microtoner is then classified to produce the microtoner (C).

International Classification:

G03G 909

US Classification:

4301071, 43013718, 4301371

Abstract:

A process for forming a particulate yellow toner for the development of latent electrostatographic latent images comprises: combining dry Pigment Yellow 185 (P. Y. 185) and a first thermoplastic polymer under conditions effective to form a predispersion of P. Y. 185 in the polymer, and combining the predispersion with a second thermoplastic polymer under conditions effective to form a yellow toner composition, from which is formed yellow toner particles.
