The surface of an electrostatic recording member in an electrophotographic recording apparatus is charged to a standard primary charge V0s. The standard primary charge on the recording member is then modulated using a first test exposure E1 to form a first exposed test area, and using a second test exposure E2 to form a second exposed test area. A first test surface potential V1 is measured in the first exposed test area and a second test surface potential V2 is measured in the second exposed test area. A measured intrinsic sensitivity bm associated with the recording member is calculated using V1 and V2. A measured intrinsic toe dm associated with the recording member also is calculated using V1 and V2. A corrective charge parameter V0i is calculated using dm, and a corrective exposure parameter E0l is calculated using bm and dm. V0 is then adjusted to equal V0i, and E0 is adjusted to equal E0i.
