PURPOSE:To decrease generation of defective transfer when humidity is high by subjecting the conductive toner image, which is formed by developing an electrostatic charge image on an image carrier by using a conductive one- component toner added with a specific ratio of a fatty acid metal salt, to pressure transfer. CONSTITUTION:A required effect is obtd. if the conductive one-component toner added with not only zinc stearate but also 0.1-10wt% other fatty acid metal salt as the additive to be added to the conductive one-component toner to prevent the defective transfer of the conductive toner image under the high humidity is used. The other fatty acid metal salts are exemplified by stearic acid metal salt, dibasic lead stearate, oleic acid metal salt, palmitic acid metal salt and the mixture composed thereof; the zinc stearate is most preferable in practicability. The generation of the defective transfer in the high humidity environment is thereby decreased. |
