Abstract

Corona charging of organic photoreceptors (OPCs) has been characterized by measurement of the time-dependent charging current. With this experimental technique, we have investigated the quantity and the dynamics of charging for times greater than the charger time constant (∼0.08 s). With a generic near-infrared sensitive OPC, we observe significant depletion of trapped charge during corona charging. The trapped charge sources are light exposure prior to charging, exposure during charging with the corona-emitted light, as well as thermal generation. This methodology provides a means of quantifying these effects and understanding the interactions of the OPC with the charging and exposure systems in an electrophotographic printer.
