    • An electrophotographic light-receiving member comprising a conductive substrate 101 and laminated thereto a non-monocrystalline material photoconductive layer 102 and a surface layer 103. The photoconductive layer 102 is mainly composed of silicon atoms and contains at least carbon atoms and hydrogen atoms. The percentage of carbon atoms having a carbon-carbon bond in the photoconductive layer is controlled to be not more than 60% based on the whole carbon atoms contained therein, and, in an instance in which a blocking layer 104 is provided between the conductive substrate 101 and the photoconductive layer 102, the percentage of carbon atoms having a carbon-carbon bond in the blocking layer is also controlled. This makes it possible to prevent clusters of carbon atoms from being formed in the photoconductive layer or blocking layer. Making the carbon atoms have a uniform distribution in the silicon film enables improvement in electrophotographic performances such as charge performance, sensitivity, residual potential, ghost-free properties, etc.
    • 一种电子照相光接收元件,包括导电基底101并且层压在非单晶材料光电导层102和表面层103上。光电导层102主要由硅原子组成并且至少含有碳原子和氢原子。 光电导层中具有碳 - 碳键的碳原子百分数被控制在不超过其含有的全部碳原子的60%以下,并且在导电性基材中设置有阻挡层104的情况下 101和光电导层102,也控制了在阻挡层中具有碳 - 碳键的碳原子的百分比。 这使得可以防止在光电导层或阻挡层中形成碳原子簇。 使碳原子在硅膜中具有均匀分布,可以改善电荷性能,如充电性能,灵敏度,残留电位,无重影性能等。
