ABSTRACT:
An electrophotographic printing machine in which an original document is reproduced on a copy sheet. The printing machine includes a photoconductive belt arranged to move in a recirculating path. As the photoconductive belt moves through a first cycle, a combined charging-transferring unit charges at least a portion of the photoconductive belt, and a combined exposing-discharging unit focuses a light image of the original document thereon. This records an electrostatic latent image on the photoconductive belt which is developed by a combined developing-cleaning unit. During the second cycle, the charging-transferring unit transfers the toner powder image to the copy sheet, and the combined developing-cleaning unit removes residual particles from the photoconductive belt. After cleaning, the combined exposing-discharging unit illuminates the photoconductive belt to eliminate any charge remaining thereon.
