PURPOSE:To facilitate control of band gaps by using a photosensitive layer having a layer region obtained by alternately laminating, in plural times, 2 kinds of ultrathin films different in the proportion of constituent atoms and continuous in the distribution of their concentrations in each interface between each couple of the adjacent ultrathin films. CONSTITUTION:The photoreceptive member has a substrate 300 and the photosensitive layer 301 composed of a nonmonocrystalline material and having a layer region obtained by alternately laminating the 2 kinds of ultrathin films different in the proportion of a constituent atoms and continuous in the distribution of their concentrations in each interface between each couple of the adjacent ultrathin films. Here, the proportion of constituent atoms means xi/SIGMAxi, where each of x, x1, x2,...xi is the number of the constituent atom, and it is possible for xi to be 0. The layer 301 is made of the nonmonocrystalline material, and obtained, for example, by alternately laminating the ultrathin films made of a-Si(H,X) and those made of a-Si(O,C,N)(H,X) in plural times. |
