Mass transfer of charge by injection may be controlled by use of the semi-conductive or photoconductive properties and energy levels of electrostatographic developer coating materials to significantly alter their charge injection char-acteristics in a kinetically controlled situation relative to a thermodynamic equilibrium state. The energy gap between the highest occupied energy level or orbital of one material and the lowest unoccupied orbital of the second material as well as the thickness of the coating material governs the process.
