摘要:
A scavengeless development system for use in highlight color imaging comprises. AC biased electrodes (46) positioned in close proximity to a magnetic brush structure (56) carrying a two-component developer to cause a cloud of toner to be generated which noninteractively develops an electrostatic image. The two-component developer includes a mixture of carrier beads and toner particles. By making the two-component developer magnetically tractable, the developer is transported to the development zone as in conventional magnetic brush development where the development roll or shell of the magnetic brush structure rotates about stationary magnets positioned inside the shell.
