A transfer sheet capable of applying a colored pattern to a final support material through the application of heat and pressure. The transfer sheet includes a carrier sheet having a colored pattern printed on a surface thereof. A digitally controlled color printer is used to print a colored pattern on the surface of the carrier sheet. A layer of white colored material is printed over at least the color pattern with a digitally controlled color printer. A layer of glue is deposited over the layer of white colored material. The layer of glue may also be printed over the white colored material by the digitally controlled color printer, or by a separate device, if required.

A photoconductive imaging member comprised of a supporting substrate, a hole blocking layer thereover, a photogenerating layer and a charge transport layer, and wherein the hole blocking layer is comprised of a polymetallosiloxane.

Photoconductive imaging members with polymetallosiloxane layers

An electrostatographic imaging member composed of: (a) a substrate having a metal surface; (b) a metal layer having less than about 1% by weight oxygen atoms based on the weight of the metal layer, bonded to the substrate metal surface, and wherein the metal layer has a composition different from the substrate metal surface; (c) a charge blocking layer including a metal oxide over the metal layer, wherein the charge blocking layer fails to function also as a light reflection preventive layer; and (d) at least one imaging layer.

Full process color imaging using black, magenta, cyan and yellow toners. A photoreceptor is utilized which is responsive to two beams of a dual wavelength laser diode exposure device or of Light Emitting Diode (LED) exposure devices operating at two different wavelengths. One of the light beams emitted by the exposure device is utilized to imagewise discharge the photoreceptor through the magenta and yellow toners while the other beam is used to imagewise expose the photoreceptor through the cyan toner.

A method and system for informing a user about characteristics of a marking material cartridge in a printing system. The system calculates a number of pixels being rendered in a present job and calculates an amount of marking material used to render the present job. The system also calculates a total area coverage to date for the marking material cartridge. Form this information an expected number of pages that the marking material cartridge can render is determined and displayed. The system determines a date when marking material in the marking material cartridge will be depleted and displays the date. The system also calculates an average coverage amount for a page being presently rendered. It can also calculate per page costs of the page currently being printed, and the pages printed to date. Additionally, the cost benefits of draft or other reduced print quality modes can be calculated and displayed. The method and system is equally applicable to black and white or color printing.

An electrophotographic imaging member is disclosed including a support substrate having a two layered electrically conductive ground plane layer comprising a layer comprising zirconium over a layer comprising titanium a hole blocking layer, an adhesive layer comprising a copolyester film forming resin, an intermediate layer over and in contact with the adhesive layer, the intermediate layer comprising a carbazole polymer, a charge generation layer comprising a perylene or a phthalocyanine, and a hole transport layer, said hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from said charge generation layer and transporting said holes through said charge transport layer.

Ionographic imaging members include an electrically conductive layer and a dielectric layer which contains boron nitride. The dielectric layer may contain boron nitride alone or boron nitride dispersed in a binder. Methods are provided for preparing and using such imaging members.

Ionographic imaging members and methods for making and using same

An ionographic imaging member containing a conductive layer and a uniform and continuous dielectric imaging layer free of voids, the imaging layer having a dielectric constant of from about 1.5 to about 40 and a thickness of at least about 45 micrometers, the thickness divided by the dielectric constant having a value of from about 30 to about 60 micrometers. This member may be used in an ionographic imaging process.

Ionographic imaging system

A corona discharge device including a corona discharge electrode in contact or closely spaced from a conductive shield electrode, the discharge electrode comprising a conductive wire coated with a relatively thick dielectric material so as to prevent the flow of conduction current therethrough. When the electrode is spaced from the shield, it is supported along its length on a dielectric surface and when it is in contact with the shield, the shield itself may provide the lengthwise support for the wire, or the support may alternatively be provided by a dielectric substrate on which the shield is carried. The delivery of charge to the photoconductive surface is accomplished by means of electric field separation of charges produced by the discharge electrode. These charges are produced by an alternating voltage applied to the discharge electrode. The flow of charge to the surface to be charged is regulated by means of a d.c. voltage bias applied to the shield electrode.

Compact corona charging device

A corona charging arrangement comprising a plurality of charging devices formed onto a unit. Each of the devices is rotatable to an operative position in which it is coupled to suitable terminals for applying energizing potential thereto, the operative position being selected so that charge therefrom is deposited on the imaging surface.
