ABSTRACT:
In an electrostatographic apparatus (11) such as a facsimile receiver, an electrical discharge electrode assembly (14) progressively forms an electrostatic image on an endless belt (12) as the belt (12) moves relative thereto. The belt (12) comprises a transparent substrate layer (12a) on which is formed a photoconductive layer (12b) and a dielectric layer (12c), with the electrostatic image being formed on the dielectric layer (12c). A lamp (26) illuminates the photoconductive layer (12b) to vary the conductivity thereof with an intensity according to the speed of movement of the belt (12).
