A toner for a two component developer used in a high speed computer output printer has about 20 parts gelled styrene/acrylic resin, 40 parts acrylate resin, about 13 parts hydrogenated wood rosin ester with pentaerythritol, and about 18 parts rosin ester of pentaerythritol, as well as carbon black and a charge control agent. Exceptional improvement is noted in carrier deterioration, fuser roller life and photoconductor filming.

A process for dip coating, particularly vertical dip coating, the topcoat layer onto fuser belts used in electrophotographic processes is disclosed. In this process, a C -C alkanol, such as isopropyl alcohol is added to the solvent system for the fluorocarbon topcoat layer. The use of alcohols in this way provides an efficient and effective method and a topcoat layer which is smooth, uniform and has a good finish.

A hot roll, for use in a xerographic, dry-release, hot roll fuser, is made by a method which adds iron-containing, magnetically permeable, particles to the elastomer as the elastomer is mixed. The particles may be pre-coated with a silane adhesive promoter. The mixed elastomer is then injected around a hollow, cylindrical aluminum core. As the elastomer sets up, in the mold, a magnetic field is applied such that the iron-containing particles migrate toward the metal core, and away from the exterior surface of the elastomer. This exterior surface will later be used to fuse xerographic toner. After the elastomer has set, its external surface is ground slightly, to produce a true circular-cylinder, but without exposing the underlying, more dense, layers of iron particle filler. As a result, the elastomer-to-core interface is mechanically strong, and yet the fusing property of the elastomer is not degraded by the presence of filler.

Toner particulates include a first resin comprising a cross-linked copolymer; a second resin comprising a non-cross-linked copolymer; and a wax comprising an ethylene propylene copolymer. The cross-linked copolymer is a copolymer other than the wax comprising an ethylene propylene copolymer and the non-cross-linked polymer is a copolymer other than the wax comprising an ethylene propylene copolymer.

A hot roll, for use in a xerographic hot roll fuser, is made by coating a hollow aluminum cylinder with an elastomer, as by the use of an injection molding machine. After molding, the external surface of the elastomer cylinder is ground slightly to improve its concentricity. Thereafter, this ground external surface is subjected to the chemical influence of an acid. After a predetermined time period, the acid treatment is terminated and the roll is washed in water. The resulting hot roll, whose external surface has been chemically modified, possesses improved dry-release properties.

A high speed toner comprising a body of hybrid resin which is about 92 percent by weight polyester and 8 percent by weight polystyrene. Blended in the resin is a charge control agent, a pigment, and about 10 percent by weight of the toner of fumed aluminum oxide. Where the pigments are color-subtractive the charge control agent is a copolymer of styrene and 2-acrylamido-2-methylpropane sulfonic acid. The toner is mixed with a carrier of ferrite particles having a thick silicone coating to remain through the long life of the toner.

The present invention relates to controlling the mass flow of toner in an image forming device or a toner cartridge. The toner composition includes extra particulate additives including a conductive additive. The extra particulate additives may also include relatively small silica particles or relatively large silica.
