A toner for developing electrostatic images and a process for producing the same is disclosed. The process comprises after applying ultrasonic waves to raw materials-mixture comprising addition polymerizable monomer(s), coloring agent(s) and water as indispensable components in the course of charging the raw materials-mixture into a reaction vessel or to a raw materials-mixture in a reaction vessel, at an application amount of from 0.05 to 50 W/l/hr. per unit treating volume and time using an ultrasonic homogenizer having frequencies of from 10 kHz to 50 kHz, subjecting the raw materials-mixture to suspension polymerization.

Process of producing electrophotographic toners comprises ultrasonic
