An encapsulated electrostatographic toner material comprising a core and a shell enclosing the core, in which said core comprises:a colorant;a polymer;a solvent having a boiling point of not lower than 180.degree. C. which is capable of dissolving the polymer of causing the polymer to swell; andan organic liquid having a boiling point in the range of 100.degree. to 250.degree. C. which is substantially incapable of dissolving the polymer or causing the polymer to swell.
