PROBLEM TO BE SOLVED: To provide the manufacturing method of a developing sleeve constituted so that electrolytic solution can be uniformly dispersed, the conductive irregularity of a covering layer is prevented from occurring, a defect is prevented from being caused by electrolytic gas and an excellent image can be formed. SOLUTION: By this manufacturing method of the developing sleeve, the covering layer is formed at the surface of a sleeve substrate 7 by electro-deposition coating by applying ultrasonic waves to electro-deposition liquid 6 from oscillators for transmitting ultrasonic waves 4 and 5 and/or generating bubbles 1', 2' and 3' from bubble generators 1, 2 and 3. Thus, the electrolytic solution can be uniformly dispersed. As the result, the developing sleeve is constituted so that the conductive irregularity of the covering layer is prevented from occurring, the defect is prevented from being caused by the electrolytic gas and the excellent image can be formed is obtained. |
