<p>A color development system (10), method, and apparatus for an electrophotographic color printer (80) which utilizes a plurality of developer rollers (22, 24, 26, 28) positioned at stationary locations between individual sources of color toner (29, 31, 33, 35) and the surface of an adjacent photoconductive drum (50). Each of these developer rollers (22, 24, 26, 28) are rotated about a fixed axis of rotation (38, 40, 42, 44) to attract charged color toners to the surface thereof while simultaneously being selectively driven by sources (45, 47, 49, 51) of AC and DC signal voltage to thereby electrostatically project colored toners of cyan, yellow, magenta, and black onto the surface of the photoconductive drum (50). Individual colored toner layers are then developed on the surface of the photoconductive drum (50) and then serially transferred to an adjacent print media (62) which passes between the surface (48) of the photoconductive drum (50) and an adjacent transfer roller (58). The print media (62) traverses a 360<0> path for the transfer thereon of each of the cyan, yellow, magenta, and black color images, and each color plane is successively fused into the paper on each 360<0> pass. The composite developed color image is then passed by a fuser roller (90, 92) and into a paper collection tray or bin (84). <IMAGE></p> |
