摘要:
The present invention relates to a process for preparing a toner for electrophotography containing a resin binder and a colorant, including the step of preparing fine particles of the resin binder to have a volume-median particle size (D50) of from 0.05 to 3 μm in an aqueous medium in the presence of a nonionic surfactant within a temperature range of from 10° C. below to 10° C. above a cloud point of the nonionic surfactant; and a toner for electrophotography obtained by the process as defined above, wherein the toner contains 60% by weight or more of a crystalline polyester and has a volume-median particle size (D50) of from 1 to 7 μm. The toner obtained according to the process of the present invention can be suitably used, for example, in development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
