摘要:
The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital, apparatuses. Embodiments pertain to an improved electrophotographic imaging member incorporating an outer layer having a groove pattern imprinted into its surface to lower friction with the cleaning blade and improve print quality and performance. Embodiments also pertain to methods and systems for making the improved imaging member.
摘要:
The presently disclosed embodiments are directed to an improved low wear overcoat for an imaging member having a substrate, a charge transport layer, and an overcoat positioned on the charge transport layer, and a process for preparing the same including combining a binder, a hole transport molecule, a melamine formaldehyde crosslinking agent and an acid catalyst dissolved in an alcohol solvent to form an overcoat solution, and subsequently providing the overcoat solution onto the charge transport layer to form an overcoat layer.
摘要:
The presently disclosed embodiments are directed generally to an improved electrophotographic imaging member in which the overcoat layer incorporates core-shell fluorinated nano- or micro-particles encapsulated in a melamine shell to reduce torque and cleaning failures during the photoreceptor cleaning process.

摘要:
The presently disclosed embodiments are directed to an imaging member having an outermost layer formulation that includes wax particles which creates a rough surface morphology for the layer and imparts increased scratch resistance, reduced torque, and improved cleaning performance to the layer. In embodiments, the outermost layer is an overcoat layer used for an improved imaging member having a substrate, a charge transport layer, and an overcoat positioned on the charge transport layer.
摘要:
A silicone overcoat (SOC) layer having a crosslinked polysiloxane composition comprising a perfluoropolyether segment are disclosed. The polysiloxane composition is the product of the hydrolysis and condensation of a SOC formulation comprising a perfluoropolyether compound, an aromatic silicon-containing compound, and a silicon-containing hole transport compound. An electrophotographic imaging member having such a SOC layer has improved properties.
摘要:
Overcoat layers, which may be useful for reducing torque in electrophotographic photoreceptors, are provided. The overcoat layers include a polymer matrix having a particulate inorganic lubricant and a particulate fluoropolymer uniformly dispersed therein. Also provided are electrophotographic photoreceptors that include a substrate and the overcoat layers, electrophotographic imaging apparatuses that include such photoreceptors, and methods for forming the photoreceptors.
摘要:
A crosslinked siloxane composite overcoat for electrophotographic photoreceptors, containing at least one siloxane-containing compound, a resin and metal oxide particles; photoreceptors containing the crosslinked siloxane composite overcoat; and image process cartridge and image forming apparatuses containing photoreceptors containing the crosslinked siloxane composite overcoat.
摘要:
Processes for preparing aromatic matrix materials by metal hydrosilylation followed by alcholysis are provided. Silicon-containing layers that contain such aromatic matrix materials are also provided, as well as electrophotographic photoreceptors and electrophotographic imaging apparatuses containing such silicon-containing layers.
摘要:
Silicon-containing layers for electrophotographic photoreceptors which have high mechanical strength, improved electrophotographic characteristics and improved image deletion characteristics even under conditions of high temperature and high humidity are provided. Such silicon-containing layers include silicon-containing compounds, which may be crosslinked, and antioxidants that can be selected from hindered phenol antioxidants, hindered amine antioxidants, thioether antioxidants and phosphite antioxidants. Electrophotographic photoreceptors and electrophotographic imaging apparatus containing such silicon-containing layers are also provided.
