Patent number: 9921508Abstract: Provided is a method of preparing a poly-silicic-ferric coagulant (PSFC) having a controlled aggregating strength. In particular, according to an embodiment, provided is a method of preparing a PSFC that may effectively suppress both formation of fine toner particles having a particle size that is smaller than a desired particle size and formation of coarse toner particles having a particle size that is greater than the desired particle size, wherein the PSFC for a toner is used in preparation of a toner by using an emulsion aggregation (EA) method. The PSFC for a toner prepared by using the method, according to an embodiment, significantly exhibits a controlled aggregating strength, and thus a viscosity of an emulsion aggregation solution for the toner preparation is appropriate, which results in suppressing production of fine toner particles and coarse toner particles. In this regard, a toner preparation yield may improve.Type: GrantFiled: March 30, 2016Date of Patent: March 20, 2018Assignee: S-PRINTING SOLUTION CO., LTD.Inventors: Sung-hwa Lee, Il-hyuk Kim, Yeong-sik Mun
