Patent ID: 7846636

Claim:
A process for producing a toner, said process comprising: (A) finely dispersing a resin binder in an aqueous medium in the presence of a nonionic surfactant to prepare a first dispersion of resin binder-containing fine particles; (B) aggregating the resin binder-containing fine particles obtained in (A) together to prepare a dispersion of mother particles; (C) adding a second dispersion of a resin binder-containing fine particles at one time or sequentially in several divided parts to the dispersion of the mother particles obtained in (B) to prepare aggregated particles thereof; and (D) coalescing the aggregated particles obtained in (C) to form toner particles; wherein the first dispersion of resin binder-containing fine particles and the second dispersion of resin binder-containing fine particles may be the same or different; and the toner particles have a volume median particle size of 1 to 4 μm.
