Abstract
A charge member is positioned in contact with an image carrier and charges a surface of the image carrier. The charge member includes a support body, an elastic layer having conductivity, which is formed on the support body; and a first surface treatment layer, which contains isocyanate compound and polycarbonate compound, is formed on the elastic layer. Residual potential of the charge member in 0.1 [seconds] after corona discharge at a voltage of 6.0 [kV] is 12.16 [V] or less.
