Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE FOR IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2006113321
Kind Code:
A
Abstract:

To provide an electrophotographic photoreceptor having high wear resistance and scuffing resistance, stability and good electrical properties and giving higher image quality over a prolonged period of time.

The electrophotographic photoreceptor has at least a photosensitive layer and a surface layer in this order on a conductive support, wherein the surface layer is formed by crosslinking a mixture containing at least a trifunctional or higher functionality radical polymerizable monomer having no charge transport structure and a monofunctional radical polymerizable compound having a charge transport structure with a light energy irradiation means. In the electrophotographic photoreceptor, an ultraviolet absorber is contained in a layer located farthest from the conductive support among the constituent layers of the photosensitive layer.
