摘要： Electrographic apparatus having an improved developer metering construction provides an elongated coil spring that extends across an applicator member's transport path (from the developer supply to the development zone) to meter and mix applied developer. Spring tension can be adjusted to control developer flow. In certain embodiments the spring provides a source of reference potential for and/or triboelectrically charges the developer and can enhance magnetic mixing of the developer.

摘要： A reproduction apparatus utilizing clear marking particles in the development of an image, the clear marking particles being laid down so as to prevent offset upon fusing of an image to a receiver member. The reproduction apparatus is disclosed as including a dielectric member adapted to have latent images formed thereon. A development station, is provided including a plurality of developer units respectively containing marking particles of different colors, at least one developer unit containing black marking particles and another developer unit containing clear marking particles. The development station selectively develops latent images with marking particles from the developer units respectively. A transfer station serves to transfer developed marking particle images to a receiver member, and a fuser assembly fuses a marking particle image on a receiver member. The developing station is controlled such that the developer unit for applying clear marking particles is selectively activated to apply clear marking particles to a receiver member, the clear marking particles uniformly decreasing toward the edges of the receiver member.

摘要： A toner image is transferred from an image member to a receiving sheet through first and second intermediate members. The first intermediate member is optimized for transfer from the photoconductor and has greater affinity for the toner than does the second intermediate member, which is optimized for transfer to the receiving sheet. This three transfer system provides transfer improvement over two transfer systems.

摘要： A clear protective overcoat is provided to an image formed in a silver halide photographic element. The overcoat is formed by electrostatically applying a uniform distribution of clear toner to an imaged photographic element and then fusing the toner to form an overcoat. The toner can be applied only in a limited area of the element.
