Charge control agent (CCA) is one of materials for toner of electophotography. The role of CCA is to improve toner's tribocharging characteristics and is necessary for electrophotography. Though inflluence of CCA in toners on their tribocharging characteristics is not enough explained theoretically, tribocharge of CCA is enough useful for electrophotography. In future we have to understand the function of CCA in toner from various standpoints to development new high performance CCA.
