| titleOfInvention | Developing apparatus with an electrode wire for discharging above a breakdown voltage |
| abstract | An apparatus (4) for developing a latent image fast and uniformly with sufficient and properly charged nonmagnetic single component toner (7), includes: a developer carrying member (5), with an electroconductive base and a resistance layer thereon for carrying developer (7) at a surface moving speed VpÄmm/sÜ to a developing portion; a developer feeding member (20) in the form of a wire, disposed close to or in contact to the developer carrying member (5), to be supplied with a voltage which is higher than a discharge starting voltage at which electric discharge starts between the developer carrying and feeding members; wherein either the resisitances R1 Ä OMEGA Ü, R2 Ä OMEGA Ü of the developer carrying member (20), in case of electric current applied to the developer carrying member being, respectively, 0.04VpÄ mu AÜ and 4VpÄ mu AÜ, satisfy R1/R2<15, or else wherein a surface potential V2 ÄVÜ of the developer carrying member (5) at the developing portion and a potential V1 ÄVÜ at the base layer, in case of an applied electric current of 4VpÄ mu AÜ, satisfy 0.8<V1/V2<1.2. <IMAGE> |
