Abstract

The influence of environmental parameters on the charge acceptance and dark decay rate of organic photoconductor for temperature from -10 degree(s)C to 80 degree(s)C and relative humidity from 25% to 95% has been studied. The decreasing charge acceptance and increasing dark decay rate of the photoconductor are due to the Poole-Frenkel-assisted bulk thermal emission of free holes from shallow and deep emission center with the energies of 0.66 eV and 0.95 eV above the valence band respectively. Above 90% RH, the xerographic characteristic deteriorates due to the decrease in resistivity involving contamination of impurity ions on the photoconductor thin film surface.
