摘要:
A developer includes a carrier and a toner, wherein the toner contains toner particles of at least one binder, at least one colorant, and external additives, wherein the developer has a trimmer clogging value in relation to toner triboelectric charge and toner cohesion expressed according to the equation (−0.80+0.039×(% toner cohesion)+0.026×(toner triboelectric charge) (μC/g)) of less than or equal to about 3.2.
摘要:
Pigment particles with at least one metal oxide surface additive, wherein the at least one metal oxide surface additive is a metal oxide particle covalently bonded with at least one polycondensation polymer, wherein the pigment particle is a pearlescent or metallic pigment.
摘要:
A toner having at least one binder, at least one colorant and external additives. The external additives include at least one fluoropolymer. An electrophotographic image forming machine and method includes the toner with at least one fluoropolymer.
摘要:
Disclosed is a toner which comprises particles comprising: (a) a core comprising: (1) a first resin; and (2) a first conductive colorant; and (b) a shell comprising: (1) a second resin; and (2) a second conductive colorant.

摘要:
Toner compositions comprising toner particles including an amorphous resin, a crystalline resin and a charge control agent. The toner compositions having the charge control agent exhibit improved charge performance in the C-zone and the A-zone, and improved RH sensitivity.
摘要:
A toner composition includes core toner particles and a shell formed over the core toner particles. The core toner particles include a resin substantially free of cross linking, an optional cross linked resin, a polyester resin, and a colorant. The shell includes a resin containing charge control agent recurring units.
摘要:
A toner includes particles of a resin, an optional colorant, and an acid-containing crystalline polymeric wax, where the acid-containing crystalline wax is selected from carboxylic acid-terminated polyethylene waxes, high acid waxes, and mixtures thereof, and where the toner particles are prepared by an emulsion aggregation process.
摘要:
A color image forming machine is provided having a plurality of xerographic marking engines, each forming associated color separations that are combined to produce a color print image. Each marking engine includes a dual replenisher assembly having first and second reservoirs containing respective toners of different gloss levels. The reservoirs each include one or more augers separately and independently controlled for dispensing the respective toners into a developer to continuously vary the gloss level of the toner in the developer.
