An encapsulated electrostatographic toner material preferably employable in a pressure fixing process and improved in the fixability after storage of the toner material comprising a core and a shell enclosing the core, in which: said core comprises, a polymer, a solvent having a boiling point of not lower than 180 DEG C. which is capable of dissolving the polymer or causing the polymer to swell, a colorant and a particulate magnetizable substance hydrophobically treated or coated on the surface; and said shell is prepared by an in-situ polymerization process such as an inner polymerization process or an outer polymerization process. |
