摘要：
A process for producing a liquid developer includes: providing a dispersion liquid containing an aqueous dispersion medium and toner mother particles including a rosin resin; chemically modifying surfaces of the toner mother particles with an amine-based material by mixing the amine-based material with the dispersion liquid to obtain toner particles; and dispersing the toner particles in an insulating liquid.
