PROBLEM TO BE SOLVED: To realize a developing apparatus with which high-image quality development surpassed in toner releasability and wear resistance and improved in reproducibility of a medium contrast is made possible. SOLUTION: The one-component developing device is characterized in that at least the surface of a developing roller 22 is composed of a material containing a polyimide denatured silicone resin and the volumetric resistance of the layer containing the polyimide denatured silicone resin ranges from 10<8> to 10<10>Ω.cm. |
