Abstract
This invention pertains to an electrographic photosensitive material comprising a blocking layer, an electroconductive substrate layer and a charge generation layer, where the blocking layer comprises TiO with an average particle size less than about 50 nm and a quaternary ammonium salt, and where the quaternary ammonium salt is uniformly distributed in the blocking layer and is less than about 5 wt % of the blocking layer. In another aspect, this invention pertains to an image forming apparatus for forming images on a recording medium comprising an imaging light having a wavelength and an organic photoreceptor having a blocking layer, an electroconductive substrate layer, and a charge generation layer, where the blocking layer comprises TiO particles and a quaternary ammonium salt, and where the quaternary ammonium salt is uniformly distributed in the blocking layer and is less than about 5 wt % of the blocking layer.
