摘要： PURPOSE: To obtain a high-quality print by developing a formed image with a specified single-component pressure fixative toner composition, then transferring the image to an appropriate substrate and fixing the image to the substrate with a specified pressure. CONSTITUTION: A single-component pressure fixative toner composition having 10 -10 Ω.cm resistivity is used in the development of an image by the electrophotographic and ion phtographic image forming systems including an electrostatic image forming method with a non-heated pressure fixing selected. This composition contains a resin grain, magnetite and a release liq. contained in the toner composition and has a conductive grain on the surface. A force of 3.5740-7.1496kg/linear mm (200-400lb/linear inch) is exerted on the toner to perform pressure fixing. Consequently, a highquality image without any background deposition is consistently obtained.

摘要： PURPOSE: To prevent the undesirable release of free wax from a toner during pulverizing operation in a toner producing process and the contamination of the subsidiary system of a xerographic machine with free wax particles by incorporating resin particles, crosslinked resin particles, a pigment, wax particles and a compatible agent contg. a graft or block copolymer. CONSTITUTION: This toner compsn. contains particles of a 1st resin such as styrene-butadiene resin, particles of a 2nd crosslinked resin of styrene methacrylate crosslinked with a component such as divinylbenzene, pigment particles of magnetite and/or carbon black, low mol.wt. wax such as PE wax and a compatible agent contg. a PP block or graft copolymer or further contains an arbitrary electrostatic charge intensifying additive, especially distearyldimethylammonium methylsulfate and carrier particles. The dispersion of toner resin particles, especially a resin-wax mixture and the dispersion of wax in the resultant toner are improved.

摘要： PURPOSE: To enable electrification for a higher triboelectric charge level than a conventional method by preliminarily blending a charge controlling additive and a pigment without a solvent, supplying the blended material to an extruder, supplying a resin through a supply port in the downstream of the supply port used for the first blended material, and then extruding the mixed compounded material. CONSTITUTION: This method includes of a process to preliminarily blend a pigment and a charge controlling additive without a solvent, a process to add and blend a resin to the mixture of the pigment and the charge controlling additive, and a process to extrude the mixture of the pigment, the charge controlling additive and the resin. The pigment and the charge controlling additive are supplied to an extruder 1 through a first supply port 13 in the upstream side and preliminarily blended and extruded. Then the resin is supplied to the extruder 1 through a second supply port 14 in the downstream side of the first supply port 13 and blended. Thereby, the obtd. toner can be charged to a higher triboelectric charge level than a toner of the same compsn. produced by a conventional extruding method.

摘要： PURPOSE: To stabilize triboelectrifying property by incorporating a positively electrifying toner composition containing a suspended polymerized styrene- butadiene polymer and a specific carrier particle. CONSTITUTION: This developer composition contains the toner composition containing the suspended polymerized styrene-butadiene resin, a pigment particle and an electrification accelerating additive and the carrier component composed of a carrier core having a coating containing a polymer mixture containing 10-90wt.% 1st polymer and 90-10wt.% 2nd polymer. And the 1st polymer is not approximate to the 2nd polymer in triboelectrification series. As a result, the developer having stable triboelectrifying property is obtained.

摘要： PURPOSE: To provide a moisture-insensitive positive charge toner compsn. having stable triboelectrification characteristics by incorporating a resin, pigment and electrification accelerating additive mixture containing a first additive of quaternary ammonium salt and a second additive of alkylammonium bisulfate. CONSTITUTION: This toner compsn. contains a resin, pigment, dye, first electrification accelerating additive of quaternary ammonium salt, preferably distearyl dimethylammonium methylsulfate, and second electrification accelerating additive containing alkyl-ammonium sulfate such as distearyl dimethylammonium methylsulfate having 1 to 20 carbon atoms in alkyl groups. The first additive chiefly acts as a charge controlling component while the second additive acts as a mixture electrification component. The obtd. toner can be used for an electrophotographic image forming device containing a normal photoreceptor which causes negative electrification.
