Abstract
Exemplary embodiments provide a digital development system and methods for making and using the system. Specifically, the digital development system can utilize a roll member that includes a plurality of actuator cells arranged in a 2-dimensional array with each actuator cell having an actuator membrane individually addressable to eject one or more toner particles adhered thereto. In addition, the digital development system can utilize an imager architecture that includes an addressing logic circuit connected to each cell to selectively control the ejection of the one or more toner particles onto an image receiving member that is closely spaced from each actuator membrane. The disclosed digital development system can be used for non-interactive development systems for image-on-image full-color printing similar to HSD (Hybrid Scavengeless Development) technology with the donor roll becoming a high quality silent imager.
