A charging roller is constituted of a shaft, a conductive elastic cylinder, and a charging layer. The shaft is integrally covered with the conductive elastic cylinder. Further, the conductive elastic cylinder is integrally covered with the charging layer. The charging roller formed in this way is restored such that it is loosely encased in a seamless charging tube having semi-conductivity.
