Abstract
A photoreceptor comprises a conductive substrate. An undercoat layer is disposed on the conductive substrate. The undercoat layer includes modified metal oxide particles and a binder resin, the modified metal oxide particles comprising metal oxide particles having an outer surface and hygroscopic polymers attached to the surface. The hygroscopic polymers are made by linking a hydrophilic polymer group to the metal oxide particles using a dithiofunctionalized phosphonatomethylaryl ligand that acts as the linking group. A photosensitive layer is disposed on the undercoat layer.
