In DC pin scorotron charging apparatus for charging a photoreceptor to a final voltage, a first DC pin scorotron charging device initially charges the photoreceptor to an intermediate overshoot voltage and a second DC pin scorotron charging device thereafter uniformly charges the photoreceptor to the final voltage. The first DC pin scorotron charging device provides a generally high percent open control grid area, a generally high emitter slope, and a generally high emitter pin current. The second DC pin scorotron charging device provides a generally low percent open control grid area, a generally low emitter slope, and a generally low emitter pin current.
