Patent ID: 8669036

Claim:
A producing method of a decolorizable toner, comprising: forming a mixed composition containing encapsulated colorant particles which are particles containing a color developable compound and a color developing agent and coated with an outer shell and have volume average particle diameter (D50) of 0.5 μm or more and 3.5 μm or less, and a polymerizable monomer by dissolving or dispersing the encapsulated colorant particles in the polymerizable monomer, making coexistence of the polymerizable monomer and a polymer of the monomer in the mixed composition to obtain the mixed composition having a viscosity at 20° C. of 0.5 Pa·s or more and 500 Pa·s or less by subjecting the polymerizable monomer in the mixed composition to bulk polymerization, dispersing the mixed composition which was subjected to the bulk polymerization in an aqueous medium; and subjecting the polymerizable monomer to suspension polymerization in the aqueous medium.
