Abstract
The present invention is an apparatus and method adaptable for use in a printing system, to measure the mass of toner developed on an electrostatic latent image produced therein. The printing system employs an electrostatic process to produce a printed sheet in response to a plurality of image intensity signals. The toner mass measuring apparatus sums a plurality of individual toner mass signals, generated as a function of the image intensity signals, to approximate the toner mass used to develop the electrostatic latent image.
