A process for producing toner particles, comprising polymerizing in an aqueous dispersion medium a polymerizable monomer composition containing at least a polymerizable monomer and a colorant, to form colored polymer particles, followed by washing and then dehydration to obtain toner particles, and feeding the toner particles into an inside-evacuatable and heatable container to make vacuum heat treatment while introducing into the container an injection medium having a temperature lower than glass transition temperature Tg of the toner particles and selected from the group consisting of i) saturated steam, ii) superheated steam and iii) high-humidity air having an enthalpy of 2,500 kJ/kg (dry air) or higher. Also disclosed is a system which carries out the above process.
