A developing cartridge includes a photoconductive body, a charging unit which charges a surface of the photoconductive body and a developing unit which forms a toner image. The charging unit includes a shaft which applies a charging voltage and which has a central axis parallel to a rotating axis of the photoconductive body, a tubular member of a conductive material which surrounds the shaft, a current carrying member which applies an electric current to the shaft and the tubular member, and a damping member which is disposed between the shaft and the current carrying member. The shaft has a middle portion which is thicker than opposite end portions in a longitudinal direction along the central axis.
