Imaging member

This invention relates in general to layered imaging members comprised for example, of a photogenerating layer; (1) a first charge transport layer comprised for example, of a charge transport component and a resin binder, and thereover and in contact with the first layer; (2) a second top charge transport layer comprised for example, of a charge transport component, and a polymer of a styrene containing hindered phenol. Advantages associated with the imaging members of the present invention, in embodiments, thereof include for example, the avoidance of or minimal undesirable migration of a hindered phenol to the photogenerating layer to thereby avoid imaging member instability, such as, electrical performance degradation, and undesirable electrical characteristics especially on long term cycling of the member; coating of two transport layers in separate passes to for example, minimize the transport layers thickness variations which variations can cause image defects referred to as rain drops; minimizing and in embodiments, avoiding an increase in the lateral surface conductivity of the member which in turn can cause image degradation, referred to as lateral conductivity migration (LCM) and which disadvantages are minimized by adding to the second transport layer a polymer of styrene having attached thereto a hindered phenol moiety or moieties. A charge transport layer for an imaging member comprising a photogenerating layer, (1) a first charge transport layer comprised of a charge transport component and a resin binder, and thereover and in contact with the first layer (2) a second top charge transport layer comprised of a charge transport component, and a polymer of a styrene containing hindered phenol.The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and outstanding print quality.
