Abstract
A replenisher material of toner particles and carrier particles, wherein a replenisher ratio of the toner particles to the carrier particles in the replenisher is determined as a function of at least one property of the developer and at least one operational property of an apparatus for developing an electrostatic latent image recorded on an image receiving member, and wherein the apparatus includes 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, and at least one dispenser for dispensing replenisher comprised of toner particles and carrier…
