Abstract

Exemplary embodiments provide a direct imaging system and methods for direct marking an image using the system. The disclosed direct imaging system can eliminate the creation of a latent image and can be used in an electrophotographic machine and related processes. Specifically, the direct imaging system can include a direct marking substrate (e.g., a printing substrate) and a development belt member closely spaced from the direct marking substrate. In one embodiment, the development belt member can include a plurality of actuator cells with each actuator cell controllably addressable to eject one or more toner particles adhered thereto. The ejected toner particles can transit the space between the donor belt member and the direct marking substrate, and directly marking onto the direct marking substrate forming an image.
