The present embodiments are generally directed to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital, apparatuses. More particularly, the embodiments pertain to an electrophotographic imaging member having a charge transport layer in which a charge transport molecule (CTM) concentration gradient is formed through a single coating pass using only a single charge transport layer solution, and time-of-flight based methods of measuring the CTM gradient through the thickness of the charge transport layer.

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.

The presently disclosed embodiments relate generally to an image forming apparatus including a delivery member for delivering a functional material in contact with an intermediate transfer belt such that functional material is transferred onto one or more imaging members via the intermediate transfer belt. 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.
