Zusammenfassung:	PURPOSE: To continuously regenerate even in use and to guarantee high copying image quality over a long period by providing a specific iron oxide-containing surface coating on a steel spherical nucleus sulfuric acid-treated with a specific sulfuric acid aq. solution. CONSTITUTION: The sulfuric acid heated steel spherical nucleus obtained by heating the steel spherical nucleus with the sulfuric acid aq. solution having 10 to 10 mol/l acid concentration at the time of starting the treatment by using 5×10 to 25×10 mol sulfuric acid per 1m surface area of the steel spherical nucleus is used. The iron oxide-containing surface coating film expressed by formula I, which is obtained by oxidizing with the acid or oxidizing agent having the oxidation equivalent of 5×10 to 25×10 per 1m surface area and drying at 60-150 deg.C under
