PROBLEM TO BE SOLVED: To improve wear resistance, without causing peeling, even if powder provided with solid lubricity, powder improving charge property, or the like is adopted many times, SOLUTION: This developing sleeve 9 is provided with the constitution that sleeve base body 12 and a covering layer formed by electrodeposition coating on a surface of this sleeve base body, is respectively furnished therewith, and that the electrodeposition covering layer 10 is formed, and moreover the second covering layer 11 is formed on the surface thereof, and then the electrodeposistion layer is exposed on the developing sleeve surface on the covering layer. Then, the covering layer formed on the surface of the developing sleeve base body has the solid lubricity powder or the static charge applying powder incorporated. |
