    摘要: A roller for improved conditioning of an image formed from a liquid developer comprised of toner particles and liquid carrier. A wire mesh uniformly covering an inner layer of the roller uniformly distributes an electrical bias closer to the surface of the roller and to the adjacent image bearing surface. The electrical bias has the same sign polarity as that of the toner particles of the image, to electrostatically repel and prevent the toner particles from entering the roller, and for compacting the toner particles to the image. The wire mesh reduces the electrical requirements of the materials used for the roller.

    摘要: A system for removing residual contaminants from an image conditioning apparatus that removes excess liquid from a developed image made up of toner particles immersed in a liquid carrier medium on an image bearing member. The system includes a vacuum blotting device that contacts the liquid developed image and absorbs a portion of the liquid carrier and residual contaminants remain thereon. A contact member adapted to be shifted from a non-operative position spaced from the vacuum blotting device, to an operative position in contact with the vacuum blotting device operates to transfer the contaminants therefrom. A scraper removes the transferred contaminants from the contact member. The contact member is pivotally mounted about the pivot point to effect shifting of the contact member between the non-operative and the operative position.

    摘要: An electrophotographic apparatus in which toner particles are moved from the toner hopper or dispenser cartridge to the developer housing and onto the donor roller in a single component development system for use in color reprographic systems. A rotating holey tube toner agitator is modified to incorporate structure or grooves on the outer peripheral surface. Further, by placing a shrouded toner dispense auger inside the holey tube, the development system architecture stays compact and improved toner powder pushing through the pre-load of toner on the donor roller results, thereby insuring delivery of fresh toner evenly across the length of the developer housing. With more efficient pre-load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle to cycle donor roller toner reload.

    摘要: An apparatus which develops a latent image recorded on an image receiving member with developer material. A donor roll is positioned in a chamber of a housing having a supply of developer material therein. The donor roll transports a metered layer of developer material into contact with the latent image to develop the latent image. A rotating and translating brush gently disturbs the metered layer of developer material on the donor roll. This substantially prevent the accumulation of developer material agglomerates on the donor roll so as to create a more stable, uniform developer material layer for development of the latent image therewith.
