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 are composed of a core and a coating over the core, wherein the difference between the coating and the binder refractive index values is greater than the difference between the core and the binder refractive index values; and (c) an imaging layer.
