    • 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(R.sub.2 /R.sub.1).ltoreq.4.5 wherein the untreated roller has a resistance R.sub.1 and the roller with the resin component has a resistance R.sub.2. 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.
    • 显影辊适于在其表面上承载显影剂并与其表面上具有静电潜像的感光鼓接触或靠近,由此显影剂被供应到滚筒以使潜像可视化。 显影辊包括高导电轴和在轴周围形成导电性的弹性层。 对弹性层进行表面处理以具有包含脲醛树脂和/或三聚氰胺树脂的树脂成分。 辊子满足​​log(R2 / R1)≤4.5,其中未处理的辊具有电阻R1,并且具有树脂成分的辊具有电阻R2。 显影辊不会污染感光鼓,并确保质量图像在长时间没有密度变化和背景雾的情况下再现。
