ABSTRACT:
Improved light receiving members which are characterized by having an special surface layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride or a non-monocrystalline material containing said boron nitride and trihedrally bonded boron nitride in mingled state or by having an especial surface layer constituted with a lower layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride and an upper layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride and trihedrally bonded boron nitride in mingled state. The improved light receiving members excel particularly in moisture resistance, repeating use characteristic, electrical voltage withstanding property environmental use characteristic and durability.
And the improved light receiving member are particularly advantageous when used as an image-making member in electrophotography since they always exhibit substantially stable electric characteristics without depending upon the working circumstances, maintain a high photosensitivity and a high S/N ratio, do not invite any undesirable influence due to residual voltage even when used repeatedly for a long period of time, cause either defective image nor image flow and have a wealth of cleaning properties.
