Abstract
A photoreceptor including: (a) a substrate; (b) a charge blocking layer including a plurality of light scattering particles dispersed in a binder, wherein the light scattering particles have a refractive index different from the binder and wherein the light scattering particles have a number average particle size greater than about 0.8 micrometer and have a surface roughness defined by a specific surface area greater than about 50 m.sup.2 /gm; and (c) an imaging layer.
