PURPOSE:To obtain a developing method having the most of advantages of both a two-component developing method and a one-component developing method, by forming a toner thin layer on the surface of a developer layer which is held magnetically on the outside peripheral surface of a non-magnetic cylindrical body. CONSTITUTION:A toner To which has been supplied onto a developing sleeve 4 being a non-magnetic cylindrical body is brought into contact with a carrier Ca and carried while improving the electrified potential, and passes through the opposed part to an electrification control member 9. In this case, since the negative polarity is applied to the member 9, the toner To which has been electrified to the positive polarity being opposite to said polarity is drawn out to the outside peripheral part, and a thin layer of a stable toner To is formed uniformly on the outside peripheral part. In this way, the toner thin layer which has been formed on the surface of the carrier Ca is brought into contact directly with an electrostatic latent image which is formed on the surface of a photosensitive drum 1 in a developing area X, and develops it. In this way, the purpose can be attained. |
