The figure shows an ADC system in a photocopier, Partially transparent photoconductor 2 is disposed on a transparent substrate 3 (e,g-, aluminized Mylar), Light source 4 is located adjacent the surface of the photoconductor bearing developed image or test patch 5. In opposed relationship on the opposite side of the photoreceptor is photodetector 6- Light from source 4 is directed through image 5, the photocon-ductor 2 and the substrate 3 to impinge on photodetector 6- The degree of light transmission serves as an indicator of developer quality, and output signals from the photodetector can control developability.
