    摘要: In a process for producing toner particles through granulation by a wet process, a process for producing toner particles is provided that enables reduction of water content in wet toner particle cakes obtained by separating toner particles from a toner particle dispersion in a good efficiency, followed by washing, and enables efficient wash-away of impurities remaining on the toner particle surfaces so as to promise superior image characteristics. The toner particles are produced through a filtering step in which a slurry which contains toner particles is subjected to solid-liquid separation by means of a belt filter having a pressing aeration means which carries out aeration with pressing, to form wet toner particle cakes.

    摘要: 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.
