    摘要: A composition that finds particular utility in forming a charge generating layer of an imaging member includes at least one charge generating material, at least one polymer binder and at least one oxidized polyolefin polymer or copolymer. The oxidized polyolefin is able to impart a thixotropic rheology to the composition, and also is able to act as an anti-settling and anti-sagging agent in the composition.
