<P>PROBLEM TO BE SOLVED: To prevent deterioration of an image quality. <P>SOLUTION: A charge member for charging the surface of an image carrier includes a support part, and an elastic layer 12b having conductivity, which is formed on the support body. The elastic layer 12b includes a surface treatment layer 12c formed thereon, the surface treatment layer containing isocyanate compound and polycarbonate compound. Residual potential of the charge member in 0.1 [second] after corona discharge at a voltage of 6.0 [kV] is defined to 12.16 [V] or less. If a worker's hand touches the surface of the charge roller, for example, while transporting, inspecting or installing the charge roller in an image forming apparatus, a touch mark is suppressed from being left thereon. <P>COPYRIGHT: (C)2013,JPO&INPIT |
