Abstract

Disclosed is a toner for electrophotography which has a small particle diameter, while being excellent in fixability at low temperatures, hot offset resistance and image characteristics. Also disclosed are a method for producing such a toner, a crosslinked resin particle dispersion liquid used for producing such a toner for electrophotography, and a method for producing such a crosslinked resin particle dispersion liquid. Specifically disclosed is a dispersion liquid of crosslinked resin particles having a volume mean particle diameter (D50) of 0.05-0.7 μm, which is obtained by a method comprising a step (A) for obtaining a resin particle dispersion liquid by neutralizing a resin containing a polyester having an acid group in an aqueous medium, and a step (B) for mixing the resin particle dispersion liquid obtained in the step (A) with a polymer having an oxazoline group at a temperature of 60-100˚C.
