Abstract
A mixed solution of a bismuth salt and a metal alkoxide is mixed together with an aqueous alkali solution, and a Bi12MO20 precursor, in which M represents at least one kind of element selected from the group consisting of Ge, Si, and Ti, is thereby obtained. The Bi12MO20 precursor is subjected to molding processing, the thus molded Bi12MO20 precursor is subjected to firing processing, and a photo-conductor layer is thereby produced. Alternatively, the Bi12MO20 precursor is subjected to heating processing in an alkaline liquid phase or to firing processing, and Bi12MO20 particles are thereby obtained. A photo-conductor layer is produced by use of the thus obtained Bi12MO20 particles.
