Abstract :
In digital electrophotography, the photoreceptor is discharged by exposing it to a high intensity laser beam from an imager for a very short duration in an image wise fashion. The resultant latent image on the photoreceptor surface is a function of both the photoreceptor properties the imager properties as well as the spatial and temporal exposure sequence. A generalized computational model for discharge based on charge generation, injection and transport in photoreceptor has been discussed previously S. Maitra et al., (1996). In This work we discuss the use of the domain decomposition method to enable efficient simulation of latent image for wide area exposures (such as wide lines, and solid areas). A photo induced discharge curve with a multibeam imager is simulated using this algorithm.
