Abstract
Electrostatic type copying apparatus incorporating an arrangement to control the electrostatic developing field to enhance reproduction of half-tone images. The control arrangement has an electrostatic field effect neutralizer effective to release neutralizing electrons in response to image charge conditions. Grid control and/or housing bias are employed to regulate the discharge and quantity of ions available.
