Abstract

The metal substrate of an electrophotographic member is provided with a selenium-tellurium alloy layer containing 5-30% tellurium, 10-5,000 ppm of a metallic element of the fifth main group, and 10-100 ppm of a halogen. A preferred embodiment contains 15% tellurium, 40 ppm arsenic, and 40 ppm chlorine. The addition of the metallic element of the fifth main group to the selenium-tellurium alloy results in a stabilization of charging potentials in multicycle operation. If the metal substrate is an aluminum drum, the electrophotographic member can be used as a copying drum in high-speed copiers.
