Apparatus and process are disclosed for fabricating an endless metal belt comprising a center region between a first end region and a second end region, wherein a portion of the first end region is at least 1.5 times thicker than the center region, thereby resulting in a thickened end portion.

Endless belts incorporating thickened bands

A process for preparing ultrafine pigment dispersions comprising providing a solubilized mixture of pigment-Lewis acid complex and an aprotic organic solvent; precipitating the resulting solubilized complex into a protic solvent thereby forming a dispersion of ultrafine pigment particles; removing the aprotic and protic solvents to afford a wet cake containing finely divided pigment particles; optionally neutralizing and washing the wet cake particles; and redispersing the resulting ultrafine pigment particles in an aqueous solution, an organic solvent, or mixtures thereof, and a binder resin to form an ultrafine pigment and binder resin dispersion.

Processes for pigment dispersion and articles therefrom

An electrophotographic imaging member including a charge generating layer and a charge transport layer, the charge transport layer having two or more charge transporting molecules having ionization potentials within 0.2 electron Volts of each other. This imaging member has stress characteristics that reduces curling, cracking and delamination from the substrate.

Transport layers containing two or more charge transporting molecules

Disclosed is a process for forming thin films of pigment compounds, comprising providing a solubilized pigment-Lewis acid complex contained in an aprotic organic solvent system and coating the solubilized pigment-Lewis acid complex containing solvent system on a substrate.

Photoconductive imaging members and processes thereof comprising

A layered photoreceptor is composed of a substrate, an extrinsic pigment layer that has been sensitized disposed over the substrate, and a charge transport polymer in contact with the pigment layer. A method for producing a photoreceptor comprises depositing a layer of sensitizing electron donor material in a polymer binder on a substrate. An extrinsic pigment layer is deposited on the layer of sensitizing electron donor material. A charge transport layer is deposited on the pigment layer.

Photoconductors employing sensitized extrinsic photogenerating pigments

An electrophotographic imaging member including a charge generating layer and a heterogeneous charge transport layer, the charge transport layer having regions of charge transport and inactive regions and the charge transporting regions are in contact with each other. This imaging member has characteristics that enable high quality and high contrast imaging.

Dual layer switch photoreceptor structures for digital imaging

An electrophotographic imaging member includes two charge generator layers and a charge transport layer. The first charge generator layer is fabricated in the form of a dot or line pattern and is sensitive to a wavelength region to which the second continuous generator layer is both transparent and insensitive. This imaging member may be employed in an electrophotographic imaging process to produce textual or pictorial reproduction on demand.

A vacuum evaporation container including a resistively heatable cylindrical crucible having at least one open end and having an axially aligned slot and a hollow cylindrical insert concentrically located within the cylindrical crucible, the insert having a slot aligned with the slot of the crucible, closed ends and an electrical conductivity less than the electrical conductivity of the electrically conductive cylindrical crucible. This vacuum evaporation container is employed in a vacuum deposition process.

Vacuum deposition process

A surface layer on an imaging member has a surface roughness which reduces the force necessary for blade cleaning, reduces blade edge truck, reduces blade/substrate friction, inhibits the formation of toner-type deposits on the imaging surface, and/or reduces or eliminates light interference patterns resulting from coherent light, for example, from a raster output scanner.

Overcoat for imaging members

An electroforming process is used to prepare an electroformed metal layer on the inside surface of a female mandrel to form an electroform with a hollow interior. A device may be positioned within the hollow interior of the electroform, and the interior is filled with a filling material. The electroform may then be separated from the mandrel by a force applied to the device positioned within the filling material.

Electroforms with high dimensional stability

A process for preparing a multilayered belt includes providing a mandrel having an outer electroforming surface or an inner electroforming surface; and sequentially electrodepositing both a polymer layer and a conductive layer on the electroforming surface of the mandrel to form a multilayered belt.
