  • Publication number: 20080096122
    Abstract: 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

  • Patent number: 5336577
    Abstract: A thick organic ambipolar layer on a photoresponsive device is simultaneously capable of charge generation and charge transport. In particular, the organic photoresponsive layer contains an electron transport material such as a fluorenylidene malonitrile derivative and a hole transport material such as a dihydroxy tetraphenyl benzadine containing polymer. These may be complexed to provide photoresponsivity, and/or a photoresponsive pigment or dye may also be included.
