Abstract:
A replenisher material comprised of toner particles and carrier particles, wherein a replenisher ratio of the toner particles to the carrier particles in the replenisher material is determined as a function of at least one property of a developer and at least one corresponding minimum operational property of an apparatus for developing an electrostatic latent image recorded on an image receiving medium with the developer, and wherein the apparatus comprises:a housing defining a chamber having a supply of developer comprised of toner particles and carrier particles therein,a donor member spaced from the image receiving member and adapted to transport toner particles of the developer from the chamber to a development zone adjacent the image receiving member,at least one wire positioned in the development zone between the image receiving member and the donor member,a voltage supply for electrically biasing the at least one wire during a developing operation with a current to detach toner particles from the donor member, forming a cloud of toner particles in the development zone, and developing the latent image with toner particles from the cloud, andat least one dispenser for dispensing replenisher material into the chamber.
