ABSTRACT:
Imaging apparatuses and Image forming methods are described. According to one embodiment, an imaging apparatus includes a photoconductor including an image forming surface configured to receive a latent image, a plurality of developers individually configured to provide a marking agent to the image forming surface to develop the latent image, wherein one of the developers is configured to move in a first direction with respect to the image forming surface to implement development of the latent image by the one of the developers and an other of the developers is configured to move in a second direction different than the first direction to implement development of the latent image by the other of the developers, and wherein the photoconductor is configured to provide the developed image for transfer to media after the development of the latent image by the one and other developers.
