PURPOSE:To obtain the titled body which does not change a potential by electrification and a residual potential, even in case of a repeating use by incorporating polyvinyl acetate and a specific squearic acid derivative to an electric charge generating layer. CONSTITUTION:The titled body is formed by laminated at least one of an electric charge transfer layer and the electric charge generating layer on a conductive substrate body. The electric charge generating layer contains the polyvinyl acetate and the aquearic acid derivative shown by formula I. In the formula, R1-R4 are each methyl or ethyl group, etc., X and Y are each hydrogen atom, hydroxyl, amino group, halogen atom, methyl or ethyl group. For example, the titled body is formed by laminating the electric charge generating layer 2 and the electric charge transfer layer 1 on the conductive substrate body composed of the substrate 4 and an aluminium layer 3 mounted thereon, in order. |
