Abstract

For the purpose of controlling the amount of tribo-charge on core-shell type toner, the charge impartation capability of a charge control agent (CCA) particles in the shell layer was investigated. Spherical acryl cores (Ac-core) having a particle size of 10 μm or Ac-cores having a styrene-acryl particle shell on their surface (St-Ac/Ac-cores) were used as core particles. As the CCA particles, Trianilino-triphenyl methane sulfate (TATPM, positive type CCA) particles were used. Nanometer sized TATPM particles and St-Ac particles were coprecipitated onto a core particle surface to form a positive charge imparting shell. The amount of tribo-charge q/m generated between the core-shell type particles and carrier particles was measured by the blow-off method. It was confirmed that a shell which contained an extremely small number of CCA particles shows remarkable positive charge impartation capability. The result suggests a promising manufacturing process for new types of chemical toners that realizes control of the amount of tribo-charge easily and accurately.
