An imaging system that includes a photoreceptor belt capable of having an electrostatic latent image recorded thereon, a group of developing stations capable of developing a color image on the photoreceptor, and at least one charging means and at least one exposing means to prepare the photoreceptor for desired conditions, such as creating a cleaning patch to remove toner from a toner support member associated with one of the plurality of developing stations.

Method and apparatus for a non-contact direct transfer imaging system

The present invention is directed to a non-contact, single-component developing system for electrophotographic machines that effectively reduces the impact of adhesion forces on the development process. The developing system of the present invention utilizes a single-component toner that tends to reduce the adhesion forces that hold the toner particles on a toner support member. Preferably, the toner is combined with large and small silica particles having a concentration by weight that results in an optimum surface coverage of toner particles by large and small silica particles that facilitates a reduction in the adhesion forces holding the toner particles on the toner support member.

Method of using variably sized coating particles in a mono component developing system

An apparatus for efficiently transferring at least two subtractive color toner images simultaneously onto a substrate. The apparatus includes a photoreceptor, transfer charger, mechanism for placing the substrate between the photoreceptor and transfer charger, a plurality of print stations and a stabilizing charger unit. Each of the print stations include a charger unit, an exposure unit, and a developer unit for applying a respective color toner to the latent image formed by the exposure unit in conjunction with the charger unit upon the photoreceptor. Upon application to photoreceptor, each toner has an initial charge-to-mass ratio, which is subsequently increased to a saturated charge-to-mass ratio when the toner passes under the charger unit of a subsequent print station. Thus, the stabilizing charger unit substantially conforms the charge-to-mass ratio of the toner deposited by the last print station to the charge-to-mass ratio of the toner developed previously. This results in more homogeneous transfer characteristics for all toners. A similar method is also disclosed.
