Patent attributes
Provided is a method of producing a toner including a toner particle, the method including: a granulation step of mixing a polymerizable monomer composition containing a polymerizable monomer and an aqueous medium to form a suspension of particles of the polymerizable monomer composition; and a polymerization step of polymerizing the polymerizable monomer in each of the particles of the polymerizable monomer composition in the presence of a metal phosphate containing aluminum as a metal element to provide the toner particle, the content ratio of aluminum in the metal phosphate containing aluminum being 1.0 mol % or more and 95.0 mol % or less with respect to all metal elements, the metal phosphate containing aluminum being obtained by adding an aluminum compound to the aqueous medium and/or the suspension.
