Abstract
The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. More particularly, the embodiments pertain to an improved electrostatographic imaging member incorporating amino triphenymethane into the charge generating layer which results in a surprisingly lateral charge migration (LCM) resistant device.
Claims20
An imaging member comprising:
- a substrate;
- an undercoat layer disposed on the substrate;
- a charge generation layer disposed on the undercoat layer, wherein the charge generation layer comprises a titanyl phthalocyanine pigment and an amino triphenylmethane molecule;
- and
- a charge transport layer disposed on the charge generation layer, wherein the imaging member exhibits lateral charge migration resistance.
