The present invention is directed to a non-contact, single-component developing system for electrophotographic devices that enables high speed, high quality development and color development without an accumulator, or some other intermediate transfer member by employing a plurality of ancillary developing members operating in tandem with a toner-carrying member to facilitate toner detachment from the toner-carrying member. The developing system of the present invention utilizes high electrostatic forces to enable toner jump without AC voltages and exploits toner adhesion forces adhering toner particles to a surface (e.g., a latent image-bearing member) to facilitate high speed development.
