Abstract
An electrophotographic imaging process includes the steps of(a) providing an organophotoreceptor belt having a photoconductive element on an electrically conductive substrate and a seam;(b) providing an imaging apparatus comprising a developer roll;(c) mounting the organophotoreceptor belt on the imaging apparatus;(d) applying a first voltage to the photoconductive element;(e) applying a second voltage to the developer roll when the seam is at a distance less than 10% of the circumference of the organophotoreceptor belt from the developer roll, otherwise applying a third voltage;(f) applying a fourth voltage to the electrically conductive substrate;(g) moving the organophotoreceptor belt;(h) imagewise exposing the surface of the organophotoreceptor belt to radiation to reduce voltage in selected areas and thereby form a pattern of high voltage and low voltage areas on the surface;(i) contacting the surface with a liquid ink comprising colorant particles in an organic liquid to create an image; and(j) transferring the toned image to a receiving medium;wherein the second voltage is equal or less than the fourth voltage when the first and third voltage are positive or the second volta…
