    摘要： An electrophotographic imaging member including a supporting substrate, an optional charge blocking layer, an optional adhesive layer, a charge generating layer, and a charge transporting element including two sequentially deposited charge transport layers each including a hole transport material and an optional film forming binder. A first charge transport layer exhibits a first charge carrier transit time and second charge transport layer exhibits a second charge carrier transit time. The two charge transport layers are formed in one of two ways. First, each layer can be formed from a different charge transport material so that the charge mobility of the charge transport material of the first charge transport layer is about 4 to about 20 times lower than the charge mobility of the charge transport material of the second charge transport layer. Or, alternatively, each charge transport layer can be made using a different amount of the same charge transport material. In this case, the first charge transport layer includes of an amount of charge transport material that is about 5% to about 30% less than an amount of charge transport material used to form the second charge transport layer. In either case, the resulting electrophotographic imaging member exhibits a discharge surface potential at a light exposure greater than about 3 erg/cm2, at a post exposure delay between about 20 milliseconds and about 500 milliseconds that can be raised from about 20 to about 200 volts above a discharge potential of an imaging member having the same components as the imaging member of the present invention except having only a single charge transport layer with a thickness that is equivalent to the charge transporting element of the present invention.

    摘要： Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising a protective outer layer which comprises light-absorbing composition that substantially prevents any light absorption by the overcoat layer. The composition comprises a low strength thermal plastic resin and a high optical density yellow dye. Thus, the light-blocking protective layer reduces the intrinsic light shock suffered by conventional overcoat layers without negatively impacting electrical properties of the overcoat layer and while improving print quality.

    摘要： 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.
