Compositions including carbon nanofoam are suitable for printing and magnetic ink.

Magnetic compositions

Processes for making organic photosensitive pigments for charge generating layers of imaging members. The pigments may include titanyl phthalocyanine. The pigments may be synthesized through a partially electrochemical or purely electrochemical process. The pigments may be used in a charge generating layer of an imaging member having a substrate, the charge generating layer, and a charge transfer layer.

Organic photosensitive pigment

An electrophotographic photoreceptor and method for forming a photoreceptor is disclosed which is provided with an anticorrosion layer on the interface between the supporting substrate surface and the undercoat layer. The photoreceptor has a high mechanical strength and minimizes defects in print for longer periods of time.

Photoreceptor member

An electrophotographic photoreceptor is disclosed which is provided with an anti-corrosion layer on the interface between the substrate surface and hole blocking layer. The photoreceptor has high mechanical strength and minimizes defects in print for longer periods of time.

A photoreceptor and method of forming the same is disclosed. A photoreceptor includes a substrate, an undercoat layer, and an imaging layer. The undercoat layer comprises a single, non-porous anodized aluminum layer that has an impedance of less than about 50 Kohm. The single, non-porous anodized aluminum layer may be used as the undercoat layer alone, or may be part of a multi-layered undercoat layer system that includes additional layers of other undercoat materials. The use of the non-porous anodized aluminum layer provides the photoreceptor with an extended effective life.

Multi-layer photoreceptor

An ink delivery device for depositing ink onto a media includes an ink reservoir, a reaction chamber situated near the reservoir, and a valve situated between the reservoir and the reaction chamber. A method of depositing ink onto a media is also disclosed.

Ink delivery system

A photoreceptor aluminum alloy substrate is prepared with specific roughness characteristics and an oxide layer for use in multi-layered electrophotographic photoreceptor. A photoreceptor substrate, or drum, is placed in a lathe and turned using a polycrystalline tool to achieve specific roughness characteristics. A oxide layer is then allowed to form on the roughened photoreceptor substrate. The roughened surface of the photoreceptor aluminum alloy substrate in conjunction with the oxide layer on the roughed surface reduces variances in surface energy across the photoreceptor substrate, and eliminates, or greatly reduces, a number of Tiger Stripe and Tiger Tail defects that may occur in an undercoat layer subsequently applied to the roughened photoreceptor substrate. The approach eliminates the need for wet honing and thereby significantly reduces the complexity and cost of fabricating a multi-layered electrophotographic photoreceptor.

Lathe surface for coating streak suppression

The present disclosure provides photoreceptors and methods for fabricating photoreceptors. Photoreceptor device surfaces and fabrication methods have been designed to suppress a 'plywood effect.' One method includes providing a substrate, rotating the substrate, lathing the substrate with a cutting tool and a cutting fluid by at least one pass, cleaning the substrate to remove the cutting fluid, and depositing onto the substrate at least one layer.

Substrate with plywood suppression

A silencer secured to the inside of a drum, for example, by an adhesive, is directly attached to flanges on either end of the silencer and drum. The flanges may be attached to the silencer without the need for a compression fit, for example, by sonically welding the flanges to the end(s) of the silencer.

A mounting apparatus for mounting a hollow work-piece on a machine includes a circumferential groove formed into an outer surface of a cylindrical supporting fixture of the machine, a dampening plug assembly for positioning inside the hollow workpiece adjacent the cylindrical supporting fixture, and an end pressure reducing device for mounting within the circumferential groove for centrifugally supporting and enabling the reduction of machining-induced pressure from the end of the hollow workpiece.

Apparatus for mounting a hollow work piece

A process including: (a) creating an electrolytic cell composed of a metal surface as a first electrode, a second electrode, and an electrolytic solution, wherein the metal surface has a plurality of metal fibers connected to the metal surface; and (b) treating electrochemically the metal surface with externally supplied power to the electrolytic cell to sever a number of the metal fibers from the metal surface to result in severed metal fiber fragments unconnected with the metal surface.

Electrochemical process to sever metal fibers

A process including: creating a galvanic cell composed of a substrate as an anode, a cathode, and an electrolytic solution, wherein the substrate includes a metal surface having a plurality of metal fibers connected to the metal surface, wherein the cathode is selected to be more noble than the metal surface resulting in the anode being the working electrode, wherein the galvanic cell spontaneously electrochemically treats the metal surface in the absence of power externally supplied to the galvanic cell; and allowing the spontaneous electrochemical treatment of the metal surface to continue for a time sufficient to sever a number of the metal fibers from the metal surface to result in severed metal fiber fragments unconnected with the metal surface.

Process to sever metal fibers using galvanic cell

A honing means produces sonic waves that suspend and propel a honing medium against a surface of a substrate. The honing medium impinges on the surface of the substrate and alters the substrate's surface roughness. The substrate and the honing means are positioned relative to each other to ensure substantial surface roughness uniformity.

Sonic honing of substrates

A method of electroforming a non-ferromagnetic substrate for use in an electrostatographic imaging member includes electroforming a non-ferromagnetic substrate of nickel and one of phosphorus, tin and copper. The substrate can be cylindrical shaped and have a substantially constant inner diameter and outer diameter along a length of the substrate. The substrates can be used in various electrostatographic imaging members including electrographic and electrophotographic imaging members. The methods of this invention can provide seamless imaging members such as photoreceptors that can be used in apparatus that include magnetic developer systems, without adversely interacting with magnetic brushes and magnetic toners.
