Liquid immersion development apparatus having efficient charge
dissipating development electrode
摘要:
In an electrostatographic liquid immersion development (LID) reproduction machine having an image bearing member having an image bearing surface, a development apparatus having a development electrode for forming a development nip with the image bearing surface and for effectively dissipating residual counter charges from the development nip. The development apparatus includes a housing mounted against the image bearing member and defining a sump portion, a conduit member having a development opening, a recovery chamber, and an opening into the recovery chamber. The development electrode consists of a conductive development shoe and a bias source connected to the development shoe. The development electrode is mounted across the development opening of the conduit member, and closely spaced from the image bearing surface for forming the development nip. Importantly, the development electrode has pores therethrough for preventing undesirable residue build-up on the development shoe, and thereby effectively dissipating residual counter charges from the development nip, thus increasing developability of image areas and cleanliness of image background areas.
