PURPOSE:To enhance durability and light responsivity by forming a specified electric charge generating layer and a specified charge transfer layer on a substrate. CONSTITUTION:The photoreceptive member has the substrate 301 and the charge generating layer 305 having a receptive function of electromagnetic wave energy and generating charge carriers, and obtained by alternately laminating, in plural times, 2 kinds of ultrathin films different in the proportion of constituent atoms, and a charge transfer layer for transferring the charge carriers generated in the layer 303. This transfer layer is made of a nonmonocrystalline material containing Si atoms and at least one kind of atoms selected from O, C, and N atoms, and it has the concentration distribution of the constituent atoms changed in the layer thickness direction. The proportion of the constituent atoms means Xi/SIGMAXi, where each of X1, X2,...Xi... is an atomic concentration of each constituent atom, and each may be 0. |
