The covering layer is formed on the outer circumferential surface of the conductive supporting body by carrying out drying in a temperature range which extends from the temperature that is 40°C lower than the boiling point of the solvent contained 60 mass % to 95 mass % to the temperature that is lower than the boiling point of a solvent containing 60 mass % to 95 mass % of the total weight quantity of the solvents. Next, drying is carried out above the boiling point of the solvent having the highest boiling point among the solvents containing 5 mass % to 40 mass % of the total weight quantity of the solvents.
