Abstract

High resolution latent image formation is an important step in electrophotography to achieve high quality prints. Presently, analytical models exist for the other important steps: photoconductor charging, development (both single and dual component), and transfer. We present here an analytical model of charge image generation on the surface of an organic photoconductor due to laser exposure. The inputs to the model include laser intensity profile as a function of time, quantum efficiency of the charge generation layer, hole mobility of the charge transport layer, and initial charge density on the surface of the PC. The output of the model is the PC surface charge map as it evolves in time, which is a key input to the toner development process in electrophotography.
