Disclosed herein is an electrophotographic imaging member comprising a substrate, and a charge generating layer containing a phthalocyanine pigment, a binder, and a solvent. The charge generating layer has a pigment particle separation distance of 28 nm or less after evaporation of the solvent. A coating system, a method of making an electrophotographic imaging member, and a method of printing also are disclosed.

Electrophotographic imaging member and method of making same

An anticurl backing layer dispersion, including: a volatile carrier liquid, solid organic or inorganic particles, and a surfactant, wherein the dispersion does not include a binder. An anitcurl backing layer composition including the above-described dispersion, a binder solution comprising a binder and a volatile carrier liquid, and optionally a resin, is also disclosed.

Anticurl backing layer dispersion

Disclosed herein is an electrophotographic imaging member comprising a substrate, a charge transport layer and an overcoat layer formed by combining a film forming binder and a hole transporting hydroxy triarylamine compound having at least one hydroxyl functional group that is linked to a ring carbon of an aryl group by an alkyl group having 1 to 12 carbon atoms and is capable of forming at least one of a chemical bond and a physical bond with the film forming binder. Also disclosed is an electrophotographic imaging member with an overcoat layer formed by combining a film forming polycarbonate binder, a hole transport material, a surface energy reducing silicone material comprising a crosslinkable acrylate monomer, and a solvent. Coatings and methods of forming imaging members also are disclosed.

Overcoat for electrophotographic imaging member and methods of making and using same

Imaging members useful in electrostatographic apparatuses, including printers, copiers, other reproductive devices, and digital apparatuses. More particularly, imaging members having nano polymeric gel particles embedded into one or more layers of the imaging member that provide for increased mechanical strength and improved wear.

Imaging member having nano polymeric gel particles in various layers

A charge generating composition including at least one charge generating material, at least one polymer binder, and at least one styrene-containing copolymer is disclosed.

Charge generating composition

A method for forming images including a) depositing an electrostatic latent image on a charge retentive surface of a photoreceptor member having a substrate; a charge transport layer with charge transport materials; and an overcoat layer positioned on the charge transport layer, wherein the overcoat layer includes a crosslinkable alcohol-soluble polyamide; and wherein the overcoat layer further includes additives having titanium dioxide, silica, a crosslinking agent, a deletion control agent, and a charge transport molecule; and b) applying a developer material via a development component to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface, wherein the developer material comprises emulsion aggregation toner, and further wherein at least one of the additives create a texturized surface on the charge retentive surface thereby reducing the contact area between the emulsion aggregation toners and the charge retentive surface enabling increased cleaning of toners.

Method for imaging with imaging member having filled overcoat layer

An electrophotographic imaging member includes a substrate, an optional intermediate (undercoat) layer, a photogenerating layer, which can be a single layer of include separate charge generating and charge transport layers, and an optional overcoating layer, wherein the photogenerating layer or a sub-layer thereof include a carbon nanotube material.

Photoreceptor

Imaging members useful in electrostatographic apparatuses, including printers, copiers, other reproductive devices, and digital apparatuses. More particularly, imaging members having nano-sized particles serving as fillers dispersed or contained in one or more layers of the imaging member that provide for increased mechanical strength and improved wear.

Imaging member having nano-sized phase separation in various layers

A fuser member includes a substrate and an outer layer including a polymeric material and a methacrylate-based fluorosurfactant.

Fuser member

Photogenerating layers of photoreceptors are provided utilizing a photogenerating component/resin dispersion formed in a low boiling point solvent.

Photoreceptors

A photoconductive imaging member containing a photogenerating layer, and a charge transport layer containing a binder and a polyol ester.

Photoconductive members

Particulate material concentration of a dispersion is detected by providing a known amount of dispersion including particulate material, a solvent, and other optional components; centrifuging the dispersion and separating the particulate material from the dispersion; drying the particulate material; and weighing the particulate material to determine a particulate material concentration of the dispersion.

Direct method to determine particulate concentration in a dispersion

A photoconductive member containing a supporting substrate, a photogenerating layer, and a charge transport layer and wherein the photogenerating layer comprises a photogenerating component, and an electron transport component.

Imaging members

A process for preparing a charge generating layer comprising dispersing photoconductive phthalocyanine particles in a polymer matrix, the matrix comprising a polymeric film-forming reaction product of vinyl chloride, vinyl acetate, maleic acid, and hydroxyalkyl acrylate, in a solution of n-butyl acetate and methyl isobutyl ketone. An electrophotographic imaging member is also prepared comprising a charge generating layer prepared according to this process.
