IMAGE DENSITY TEST CIRCUIT FOR AN ELECTROPHOTOGRAPHIC COPIER

An image density test circuit for an electrophotographic copier includes a light source (33) and a sensor (34) for monitoring a test patch (30) produced on the imaging element (26) of the copier. While the bare photoconductor is being sensed an energising circuit sets the light source output to a fi...
