摘要:
Processes for making organic photosensitive pigments for charge generating layers of imaging members. The pigments may include titanyl phthalocyanine. The pigments may be synthesized through a partially electrochemical or purely electrochemical process. The pigments may be used in a charge generating layer of an imaging member having a substrate, the charge generating layer, and a charge transfer layer.
