ABSTRACT:
A process and apparatus for charging insulating toner particles wherein there is provided a charging roll containing a triboelectrically active coating, and weakly charged toner particles are transported into contact with the coating contained on the charging roll, this contact being accomplished in a charging zone situated between the charging roll and the transporting mechanism. As a result of contact between the weakly charged toner particles and the triboelectrically active coating contained on the charging roll there is imparted charges of either a positive or negative polarity to the weakly charged toner particles. The apparatus and process of the present invention are useful, for example, in electrostatographic recording imaging devices.
