ABSTRACT:
A process for producing an electrophotographic toner in one step by suspension polymerization of monomers capable of forming a fixing resin. In a first embodiment, the suspension polymerization is carried out in the presence of a specific suspension stabilizer and a radical polymerization initiator. In a second embodiment, the suspension polymerization is carried out while applying ultrasonic radiation of a fixed frequency. The process gives a toner having a uniform particle size distribution.
