Abstract
In the present invention, disclosed is an organic photoreceptor comprising a conductive support and provided thereon, a photosensitive layer and a protective layer provided on the photosensitive layer, the protective layer formed with alumina particles each comprising a reactive organic group. Also provided is an organic photoreceptor with which electrophotographic images having high durability together with high image quality can be obtained by improving a wear property of the organic photoreceptor up to the same level as that of an amorphous silicon photoreceptor, as well as by improving image flow and image blur which are easy to be generated at high temperature and high humidity.
