摘要： The present invention relates to a polymerized toner prepared by suspension polymerization. Provided is a method for preparing a toner comprising the steps of (1) preparing a toner by suspension polymerization using a water-based dispersant that adjusts size of emulsion particles, which are formed as byproduct, to 0.05-2 μm; and (2) removing the dispersant from the toner surface, refining the toner, so that concentration of the emulsion particles becomes 0.01-2 wt % of the toner, and filtering and drying the toner in vacuum. Also provided is a toner prepared by suspension polymerization using a water-based dispersant, concentration of emulsion particles being 0.01-2% and diameter of the emulsion particles being 0.05-2 μm. The present invention provides a good toner having fusing property and developing property by effectively controlling the concentration of emulsion particles formed during suspension polymerization as byproduct.

摘要： 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.
