Toner for developing electrostatic images and a method of manufacturing the same |
| abstract |
Spheroidal toner for developing electrostatic images is composed of a binding resin as its main component in which at least carbon black and a dispersion stabilizer for the carbon black are contained, the conductivity of the toner being in the range of 5 × 10⁻¹¹ to 5 × 10⁻⁹ S/cm and is manufactured by the steps of: forming grafted carbon black by prepolymerization of polymerizable composition containing carbon black and a monomer forming a binding resin; adding a carbon black dispersion stabilizer to the prepolymerized composition; and suspending the composition in an aqueous medium and polymerizing the suspended particles in the presence of a polymerization initiator. |
