Xerographic discharge characteristics of photoreceptors with bulk generation. II. Time-varying exposure

Abstract

The theoretical studies of xerographic discharge with bulk generation have been extended to the case where the exposure time is not short compared to the carrier transit time. The theory has been developed to treat any time‐varying exposure. However, only the numerical results for finite and continuous step‐function exposures are presented. The results are discussed in terms of the residual potential, exposure to generate one CV 0, time to discharge a given fraction of the initial potential V 0, and the contrast potential. The effects of the field dependences of carrier mobility and carrier generation efficiency, the asymmetry of the hole and the electron mobilities, the light flux level, the exposure time, and the optical density of the photoreceptor on the above quantities are investigated.
