Dosed charging: Application to the investigation of papers

Abstract A dosed charging–discharging method was applied to an investigation of the paper charging properties which may be important in toner transfer in electrophotographic printers and copiers. This investigation method, which is new for paper substrates, made it possible to reveal some characteristics of paper charging and discharging processes: the dependence of charge acceptance on charging intensity, which is different for coated and uncoated papers, the change in paper charging properties during charging, unconventional charge acceptance and potential decay dependence on thickness at higher relative humidity, and the role of paper polarization in the discharge of paper.
