摘要： An apparatus for developing a latent image recorded on an imaging surface, including a housing defining a reservoir storing a supply of developer material including toner. A donor member is spaced from the imaging surface, for transporting toner on an outer surface of the donor member to a region opposed from the imaging surface. A mag roll loads toner onto a region of the outer surface of the donor member. A charging device ion charges the toner loaded on the region of the donor member. An AC/DC voltage supply for biasing the donor member positioned in close proximity to the imaging member to detach toner from the donor member as to form a toner cloud for developing the latent image. A second charging device discharges and removes residual toner on the region of the donor and returning the toner to the reservoir.

摘要： A system for removing excess carrier liquid from an electrostatic image developed with liquid developing material made up of toner particles immersed in a liquid carrier medium on an image bearing member. The system includes an absorbent contact roller for absorbing at least a portion of the liquid carrier off of the liquid image, and vacuum source coupled to the contact roller for generating both negative pressure at the surface of the roller to draw the absorbed liquid through the contact roller, and positive air pressure for pushing contaminated liquid out of the roller.

摘要： A method and apparatus for simultaneously developing and transferring a liquid toner image. The method includes the steps of moving a photoreceptor including a charge bearing surface having a first electrical potential, applying a uniform layer of charge having a second electrical potential onto the charge bearing surface, and imagewise dissipating charge from selected portions on the charge bearing surface to form a latent image electrostatically, such that the charge-dissipated portions of the charge bearing surface have the first electrical potential of the charge bearing surface. The method also includes the steps of moving an intermediate transfer member biased to a third electrical potential that lies between said first and said second potentials, into a nip forming relationship with the moving imaging member to form a process nip. The method further includes the step of introducing charged liquid toner, having a fourth electrical potential, into the process nip, such that liquid toner sandwiched within the nip simultaneously develops image portions of the latent image onto the intermediate transfer member, and background portions of the latent image onto the charge bearing surface of the photoreceptor.

摘要： A tandem tri-level architecture. Three tri-level engines are arranged in a tandem configuration. Each engine uses one of the three primary colors plus one other color. Spot by spot, two color tri-level images can be created by each of the engines. The spot by spot images are transferred to an intermediate belt member, either in a spot on spot manner for forming full color images or in a spot next to spot manner to form highlight or logo color images. The images created by the tri-level engines can also be transferred to the intermediate in a manner such that both spot next to spot and spot on spot transfer is effected.

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.

摘要： Developer apparatus and toner dispenser system therefor that is capable of modulating toner addition very uniformly, not only across the width of a developer housing but selectively along a length of a developer member in an area that was previously depleted by its passage through a development nip. Thus, toner is dispensed only where it is needed.
