Advancements in Photolithography Techniques

This review traces the history and development of organic photoconductors (OPCs), the multilayer thin film photosensitive element in electrophotographic printers, from Chester Carlson's 1938 demonstration of xerography to the present. A brief discussion of the history of electrophotography is followed by a review of OPC basics and the development of specific charge generating materials (CGMs) and charge transporting materials (CTMs). Next is a discussion of OPC commercialization and the last section demonstrates the cycle of OPC research and development by the number of OPC presentations at international conferences.
