摘要： A process for producing toner particles is conducted by:preparing toner precursor particles containing at least binder resin and coloring agent; andspherizing the toner precursor particles to obtain toner particles;wherein spherizing steps include;(1) dispersing the toner precursor particles in an aqueous medium containing a dispersant, thereby preparing a disperse system (a);(2) dispersing oil droplet particles containing a softening agent into an aqueous medium, thereby preparing a disperse system (b);(3) preparing a mixed disperse system (c) by adding the disperse system (a) to the disperse system (b), and causing the softening agent to be absorbed by the toner precursor particles in the mixed disperse system (c); and(4) removing the softening agent from the toner precursor particles.

摘要： A toner production process comprising the step of polymerizing a polymerizable monomer in the presence of (i) base particles containing at least a binder resin and (ii) a polymerization initiator. The polymerization initiator has in one molecule a hydrophilic moiety and a hydrophobic moiety and a reactive moiety between them, and the base particles are enlarged and/or surface-modified upon polymerization of the polymerizable monomer. Also disclosed is a toner having a circularity of from 0.92 to 1.0, which is produced by this process.
