摘要:
Disclosed is an apparatus for scavenging charged particles (e.g. triboelectrically carrier particles) from an electrographic recording element. Such apparatus comprises a conductive grid (50) positioned in close proximity to the path of the recording element, and biasing means (52) for electrically biasing the grid so as to attract the charged particles from the recording element yet prevent them from depositing on, and thereby contaminating, the grid.
摘要:
Large solid areas of electrostatic images are developed by moving partially conductive developer across the image in both upstream and downstream directions with careful control of bias and speed of each developer movements to improve edge development conformity with the rest of the solid area.
