Abstract: Electrophotographic copying apparatus has charging, imaging, transferring, precleaning, and erasing facilities in a conventional sense but incorporates a combined developingcleaning unit that is operable to perform either function at the proper time during the copying sequence. A first version incorporates a photoconductor drum structure surrounded with the necessary electrophotographic elements including a single developer-cleaner unit. Another version incorporates a photoconductor belt movable forwardly and reversely. In either version, cleaning cycles may alternate with developing cycles or be activated following the production of a high number of images on the photoconductor surface. Conveniently, a magnetic brush element forms a contacting surface for conveying toner onto the photoconductor surface during developing and for scavenging residual toner from the photoconductor surface by bringing developer mixture into contact with the photoconductor surface during cleaning. Appropriate changes in biasing of the brush are made during operation.

Abstract: An electrophotographic development carrier comprises core particles coated with a mixture of a fluoropolymer and a modifying material. When utilized with appropriate electroscopic toner materials, the carrier is effective in producing a relatively negative triboelectric charging of the toner particles while it obtains a relatively positive charge. The relatively positive triboelectric characteristic is obtained by curing the coated particles through heating at a temperature less than about 700* F.
