Abstract

An electrophotographic printing machine in which a magnetic toner image is transferred to a copy sheet from a photoconductive member and fused thereto. The toner image fused to the copy sheet is magnetized and the intensity of the magnetic field generated by the toner image detected to provide a continuous indication of the quality of the toner image fused to the copy sheet.
