Abstract:
A process for producing toner particles which comprises a polymerization step of polymerizing a polymerizable monomer composition containing at least a polymerizable monomer, in a vessel holding therein an aqueous medium, wherein;a high temperature saturated steam with a temperature higher than 100Â° C. is introduced into the aqueous medium held in the vessel, at the latter half of polymerization or after the polymerization has been completed, to remove at least organic volatile components from toner particles having at least a binder resin and a colorant, said saturated steam introduced into the polymerization vessel has a temperature of from 105Â° C. to 180Â° C. and is at a pressure P (kPa) of: 126.6&lE;P&lE;1,013.3.
