20090214967 | ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE USING THE SAME - The present invention provides an electrophotographic photoreceptor having at least a photosensitive layer and a surface layer provided at a surface of the photosensitive layer The surface layer contains a first layer which is provided at the photosensitive layer side and has a refractive index of n | 08-27-2009 |
20090253061 | ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE USING THE SAME - An electrophotographic photoreceptor includes a conductive substrate, and a photosensitive layer, an intermediate layer having a thickness of 2 nm to 70 nm, and a surface layer, which are disposed in this order on the conductive substrate. The refractive index n | 10-08-2009 |
20090297217 | ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE USING THE SAME - The present invention provides an electrophotographic photoreceptor having at least a photosensitive layer and a surface layer provided at a surface of the photosensitive layer. The surface layer contains a first layer which is provided at the photosensitive layer side and has a refractive index of n1 and a second layer which is provided at the opposite side of the first layer to the photosensitive layer and has a refractive index of n2. The refractive index of the photosensitive layer, the refractive index of the first layer, the refractive index of the second layer, the film thickness of the first layer, an integer of 0 or more, and the wavelength of light with which the surface of the photoreceptor is irradiated when an electrostatic latent image is formed satisfy specific relationships. | 12-03-2009 |
