Abstract
The present invention is a method of manufacturing toner particles that includes providing a first emulsion of a first aqueous phase comprising a pore stabilizing hydrocolloid dispersed in an organic solution containing a polymer. The first emulsion is dispersed in a second aqueous phase to form a second emulsion that is sheared in the presence of a stabilizing agent to form droplets of the first emulsion in the second aqueous phase. The organic solution is evaporated from the droplets to form porous toner particles.
