Developing roller and developing apparatus |
| abstract |
A developing roller is adapted to carry a developer on its surface and come in contact with or close to a photoconductor drum having an electrostatic latent image borne on its surface whereby the developer is supplied to the drum to visualize the latent image. The developing roller includes a highly conductive shaft and an elastic layer with conductivity formed around the shaft. The elastic layer is surface treated so as to have a resin component which contains a urea resin and/or melamine resin. The roller satisfies log(R2/R1)</=4.5 wherein the untreated roller has a resistance R1 and the roller with the resin component has a resistance R2. The developing roller does not contaminate the photoconductor drum and ensures that images of quality are reproduced without a density variation and background fog over a long time. |
