Abstract
The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to a photoreceptor that incorporates a material with a high dielectric constant that improves background and print image quality.
Claims17
An electrophotographic imaging member, comprising:
- a substrate;
- an undercoat layer formed on the substrate;
- at least one imaging layer formed on the undercoat layer;
- and
- optionally an interface layer formed between the undercoat layer and the at least one imaging layer, wherein at least one of the undercoat layer and the interface layer comprises a polymer having a high dielectric constant of about 5 or greater at 20° C. and 1 kHz and the polymer comprises vinylidene fluoride.
