Abstract
An apparatus which develops an electrostatic latent image recorded on a photoconductive member employed in an electrophotographic printing machine having a finite, usable life. The apparatus employs a developer material which ages during the life of the electrophotographic printing machine. A continuous supply of carrier granules is furnished to the developer material. The addition of these carrier granules extends the useful life of the developer material so as to correspond to at least the useful life of the electrophotographic printing machine.
