摘要：
A charge roll for electrophotography wherein surface of the roll is formed from a resin layer containing BaSO.sub.4 particles coated with SnO.sub.2-x (wherein 0.ltoreq.X.ltoreq.1) is disclosed. The charge roll may comprise a roll shaft, an electroconductive elastic layer and the surface resin layer. The charge roll may further comprise an intermediate layer formed between the electroconductive elastic layer and the surface resin layer.
