Abstract
An apparatus which develops an electrostatic latent image recorded on a photoconductive member used in an electrophotographic printing machine. The apparatus employs a development material wherein developability degradates as the duration of time that the toner particles remain in the developer housing increases. Developability is significantly improved by periodically adding a flow additive material to the developer material.
