摘要： A developer station and method for an electrographic printer is provided that reduces developer agitation. The developer station includes a sump of magnetic developer, and a magnetic brush roller mounted above sump and having a rotatable magnetic core surrounded by a substantially cylindrical toning shell rotatably mounted with respect to the core. The toning shell defines a nip at its closest point to the photoconductor element. A tangent line tangent to the cylindrical toning shell at the nip is oriented substantially vertically, and the magnetic developer is applied to the toning shell at an angular distance of no more than about 120° from the nip. The toning shell may be eccentrically mounted with respect to the magnetic core and is substantially closest to the rotatable magnetic core within about +30° and −30° from the nip. Such a configuration advantageously reduces the residence time of the developer on the toning shell.

摘要： An apparatus and method for distributed mixing and transport of toner and powders in an electrostatographic printer containing at least powder and magnetic carrier. The apparatus includes a powder conveying apparatus for transporting powder in a developer station including a development station housing having two or more auger assemblies, each auger assembly including two or more screw augers supported in a channel profile. The two or more screw augers having multiple intermeshed screw blades and controlled by a conveyance controller. The conveyance controller is in communication with the powder the one or more augers, such that each auger preferentially mixes and transports in a first or second direction as the powder conveying device conveys the powder in the developer sump of a print engine.

摘要： A composite toner image made up of first and second toners is formed on an image member. A first electrostatic image of a first polarity is formed on the image member. That electrostatic image is toned with a first toner of the first polarity. The image member is imagewise exposed to create a second electrostatic image also of the first polarity. Exposure is overlapped into the portion of the image member under the first toner image to prevent any charge on the photoconductor of the first polarity underneath the first toner image from repelling toner into the portions of the second electrostatic image that are discharged. Preferably, the second exposure is accomplished through the base of the image member in order to thoroughly expose portions of the electrostatic image underneath the first toner image.
