Abstract
Suspension polymerization toner of core-shell structure with positive charges comprises core-shell composite particles prepared by mixing composition forming toner core particles with aqueous dispersion liquid, carrying out a heating polymerization reaction to obtain suspension dispersion liquid of toner soft core particles, and carrying out a water-based polymerization reaction to form the core-shell composite particles of which an outer surface of the toner core particles are coated with the rigid shell layer with dense positive charges.
