Abstract: Disclosed is a method for producing a polymerized toner. In the method, a mixture of colloidal silica as an aqueous dispersant and a polyvinylpyrrolidone is used during suspension polymerization. The amount of polyvinylpyrrolidone/colloidal silica aggregates having a diameter smaller than 100 nm is also limited to 1% by weight or less, based on the total weight of all aggregates. A polymerized toner produced by the method has a volume average particle diameter (dv) of 5 to 10 μm and a volume average particle diameter/number average particle diameter ratio (dv/dp) of 1.5 or less. The polymerized toner is consumed in a small amount during printing. According to the method, the formation of emulsion particles having a size smaller than 0.5 μm is inhibited.

Abstract: A polymerized toner is provided. The polymerized toner comprises a reactive anionic surfactant having at least one reactive functional group. The reactive anionic surfactant is added simultaneously with a dispersant to prepare an aqueous dispersion or is added within 2 hour after a polymerization reaction of a monomer mixture is initiated in an aqueous dispersion. This simultaneous or rapid addition allows the reactive anionic surfactant to be dispersed on the surface of the toner particles. The reactive anionic surfactant is located over the entire surface of the toner particles to increase the surface charge density of the toner, achieving good charge stability and excellent imaging characteristics.
