The dipole development process develops uncharged toner into an image using a spatially modulated charge pattern to attract toner through dipole forces. This spatially modulated charge pattern is accomplished by screening the image, either simultaneous or sequential screening can be used. A typical embodiment of this technique is to charge the photoconductor, expose it to a screen, and then expose the image. This proposal eliminates the charging step and the screen exposure step.
