Abstract: Embodiments pertain to a novel imaging member, namely, an electrostatic latent image generating member, and methods for using the same, that can generate an electrostatic latent image digitally with fewer steps and without using a raster output scanner (ROS) or free charge carriers. Embodiments provide a novel way of generating an electrostatic latent image without the shortfalls suffered by current photoreceptors, such as for example, charge mobility issues, unstable cycling, surface wear, lateral charge migration and sensitivity to light shock.

Abstract: The presently disclosed embodiments relate generally to an image forming apparatus comprising: a) an imaging member, b) a bias charging roller in contact with the surface of the imaging member, and c) a delivery unit in contact with the surface of the bias charge roller, wherein the delivery unit is fabricated as a polymer matrix impregnated with functional materials, such that the functional material is transferred onto the imaging member from the delivery unit via the bias charging roller. Embodiments also pertain to an improved electrophotographic imaging member comprising a very thin outer layer on the imaging member surface, where the outer layer comprises functional materials, such as paraffin, that act as a lubricant and or a barrier against moisture and/or surface contaminants. The improved imaging member exhibits improved xerographic performance, such as reduced friction and deletions in high humidity conditions.

The first semiconducting layer comprises a first metallophthalocyanine. The second semiconducting layer includes a blend of a second metallophthalocyanine with an electron acceptor. The second semiconducting layer is located between the first semiconducting layer and the electron transporting layer. The first and second metallophthalocyanines have different valences. The complementary absorption profiles of these layers result in a device having greater absorption and efficiency than expected, without the need for a recombination layer or the need to match current between layers.
