20090297974 | CARRIER FOR AN ELECTROPHOTOGRAPHIC DEVELOPER, AND ELECTROPHOTOGRAPHIC DEVELOPER USING THE CARRIER - A carrier for an electrophotographic developer, in which a carrier core material surface is coated with a mixed resin of a fluorine resin selected from a tetrafluoroethylene-hexafluoropropylene copolymer or a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, and a polyamide imide resin, wherein the mixed resin includes a surfactant and a charge control agent, and the mixed resin has a perfluorooctanoic acid content of 100 ppm or less and an electrophotographic developer using this carrier. | 12-03-2009 |
20100009280 | Treated metal oxide particles and toner compositions - Treated metal oxide particles include metal oxide particles treated with at least a charge modifying agent. The charge modifying agent is represented by the following formula: | 01-14-2010 |
20100129750 | DISPERSIBLE NANOPARTICLES - Pulverulent particles (P) have surface groups of the general formula (1): —O | 05-27-2010 |
20110117486 | TONER COMPOSITIONS - The present disclosure provides polyesters suitable for use in forming toners. In embodiments, a polyester may be subjected to phase inversion emulsification, in which charge control agents are added so that the polyester emulsion includes charge control agents therein. The resulting polyester emulsion with charge control agents may then be utilized to form toner particles. | 05-19-2011 |
20110236817 | ELECTROSTATIC IMAGE DEVELOPING TONER, METHOD FOR PRODUCING ELECTROSTATIC IMAGE DEVELOPING TONER, METHOD FOR FORMING IMAGE, AND IMAGE FORMING APPARATUS. - An electrostatic image developing toner includes a binding resin and a release agent, wherein an organic silicon compound including a siloxane bond is present in a domain of the release agent. | 09-29-2011 |
20140120467 | TONER COMPOSITIONS - A toner having charge control agents which impart excellent triboelectric charging characteristics. In embodiments, the toner particles are made by a process in which the toner particles are made without a shell which provides homogenous distribution of the charge control agents, providing a toner with higher charge and better environmental stability | 05-01-2014 |
