<title>Photoinduced discharge curve (PIDC) of photoconductor affected by the exposure flux</title>

Abstract

Photoinduced Discharge Curve (PIDC) , which represents the photoconductor surface potential as a ftrnction of the input exposure, is a critical parameter in xerographic processes. In general, the PJDC defines a suitable exposure energy to achieve the surface potential of photoconductor for different operating conditions. In order to reach the same surface potential, one can increase the exposure energy or to increase the incident light of flux. Two experimental methods were used to measure the PIDC of organic photoconductor drum. One method is to fix the exposure spot size and changed exposure energy. Another method is to fix the flux of incident light by changing spot size and exposure energy.The light flux in our experiment was set in the range of iO' '.-iO photons/cm2*sec. The surface potential of OPC drum can be discharged to the values below -bOy when the exposure energy is in the range of 1-lOpJ/cm2.
