Abstract
A printer member adapted to be used in an ion printing device having a conductive coating positioned on a portion of the marking head near the charge receiver. The conductive coating is electrically connected to the housing in order to substantially equalize the voltage potential of the housing and marking member. The above arrangement enables the device to be set at a single operating state that would allow the device to operate very near its breakdown threshold at all humidity levels.
