ABSTRACT:
A charging member including an elastomeric member including an elastomeric material. The elastomeric material includes a polymer dispersion medium having a double oxide dispersed therein, the double oxide being a solid solution compound of oxides of at least two different metals formed by crystal lattice substitution. The at least two different metals have different valences, whereby the double oxide has an electroconductivity that is larger than that of either one of the oxides of at least two different metals when not in solution. Also, the charging member has resistance stability in the semiconductive region.
