Abstract
A charging member for use in a device, such as an electrophotographic or facsimile device, includes at least inner and outer resistance layers formed on an electrically-conductive substrate. Electrically-conductive particles dispersed in the matrix of the outer resistance layer are reduced titanium oxide which is represented by the following general formula: EQU TiOn where n is a number not more than 1.9.
