| titleOfInvention | Manufacturing method of toner |
| abstract | An object of the present invention is to provide a toner with reduced residual monomers in a toner while suppressing adhesion of the toner precursor in a centrifugal separator in a concentration step and damage to the toner precursor with high production efficiency. A granulating step of forming particles of a polymerizable monomer composition containing a polymerizable monomer in an aqueous medium, wherein the polymerizable monomer composition contains particles of the polymerizable monomer composition. A polymerization method for obtaining a toner precursor by polymerizing a monomer, and a method for producing a toner having a concentration step of increasing the solid content of the toner precursor in the aqueous medium, Produced by polymerizing using at least two or more polymerization initiators in the polymerization step, The first polymerization initiator among the polymerization initiators has a 10-hour half-life temperature of 70.0 ° C or higher and 115.0 ° C or lower, The second polymerization initiator has a 10-hour half-life temperature of 45.0 ° C. or more and 65.0 ° C. or less, and the amount of the second polymerization initiator added is 2.5 mol% with respect to the polymerizable monomer. Not less than 20.0 mol%, The concentration step is characterized by using a centrifuge. [Selection diagram] None |
