摘要： An electrophotographic image forming apparatus using a charge roller for uniformly charging the surface of a photoconductive element, or image carrier, during image formation, and a charging device having the charge roller. The charging efficiency is enhanced, and a uniform charge distribution is set up by the application of a DC voltage only. This suppresses the increase in the cost of an apparatus, the increase in power source cost, and the generation of a great amount of ozone. As a result, a charging member and a photoconductive element are prevented from being deteriorated while environmental pollution is eliminated.

摘要： In a charging device included in an image forming apparatus for charging an image carrier uniformly, a charge roller has an elastic layer and a surface layer. The elastic layer is made of a substance having a medium electric resistance and having no conductive particles dispersed therein. The surface layer is made of a non-adhering substance having a greater non-adhering property than the substance constituting the elastic layer.
