ABSTRACT:
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.
