Title: Innovations of James D. Walling
Introduction
James D. Walling is a notable inventor based in Fairport, NY (US). He has made significant contributions to the field of electrophotography, holding a total of 4 patents. His work has advanced the technology used in color imaging methods and electrostatic image development.
Latest Patents
One of Walling's latest patents is an electrophotographic color imaging method. This method utilizes an element that comprises a photoconductive layer on an electrically conducting substrate capable of transmitting actinic radiation. The photoconductive layer is responsive to this radiation, and a dielectric support is releasably adhered to the substrate. The process involves charging the surface of the dielectric support and exposing the photoconductive layer to actinic radiation to form a developable electrostatic image. This image is then developed with toner to create a first color image. By repeating this sequence, a composite color image is formed, which can be transferred to a receiving element to create a color copy.
Another significant patent by Walling is a magnetic brush apparatus for developing electrostatic images. This apparatus is designed for use in electrographic copiers and includes a non-magnetic sleeve with a rotatably driven magnetic roller. The design allows for selective reduction of the magnetic field produced by the roller, which helps avoid trailing edge development artifacts during the image development process.
