Reduction of seam mark from an endless seamed organophotoreceptor belt

摘要

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, applying a third voltage to the photoconductive element; (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 voltage is equal or greater than the fourth voltage when the first and third voltage are negative.
