CAPSULATED TONER AND ITS PRODUCTION

摘要

PURPOSE:To produce a capsulated toner well maintaining its electric conductivity, capable of surely holding a fixable material by each shell and excellent in image quality and fixability. CONSTITUTION:This capsulated toner consists of a core material contg. a fixable component, each shell coating the core material and an electric conductive material sticking to the surface of the shell and contains colorant particles and/or magnetic particles in the shell if necessary. The shell contains polyurea resin and/or polyurethane resin obtd. from a polyisocyanate monomer and a urethane modified adduct of a polyisocynate.
