An imaging member comprising:
- a substrate;
- a charge generation layer positioned on the substrate;
- at least one charge transport layer positioned on the charge generation layer;
- and
- an undercoat layer positioned on the substrate on a side opposite the charge generation layer, the undercoat layer comprising a binder component and a metallic component comprising metal thiocyanate and metal oxide;

An image forming apparatus for forming images on a recording medium comprising:
- a) a photoreceptor member having a charge retentive surface to receive an electrostatic latent image thereon, wherein said photoreceptor member comprises a metal or metallized substrate, a charge generation layer positioned on the substrate;
- at least one charge transport layer positioned on the charge generation layer;
- and an undercoat layer positioned on the substrate on a side opposite the charge generation layer, the undercoat layer comprising a binder component and a metallic component comprising metal thiocyanate and metal oxide wherein the weight ratio of the metallic component to the binder component is from about 20/80 to about 80/20;
- b) a development component to apply a developer material to said charge-retentive surface to develop said electrostatic latent image to form a developed image on said charge-retentive surface;
- c) a transfer component for transferring said developed image from said charge-retentive surface to another member or a copy substrate;
- and
- d) a fusing member to fuse said developed image to said copy substrate.
