Abstract
Image intensity adjustment in a copying machine is performed by simultaneously adjusting both a bias voltage to be applied to a developer unit of the copying machine and the intensity of light to be projected at an exposure section onto a photosensitive medium of the copying machine. Adjustment is facilitated by operatively connected variable resistors.
