Image defect reduction in image development apparatus
Abstract:
Super wire history image defects in an image development system including one or more electrode wires disposed in a gap between a toner donor roll and an imaging member are reduced by providing an initial toner composition in the image development system, the initial toner composition containing at least 30 number % fine particles having a particle size no greater than 5 μm; and providing replenisher toner into the development system to replenish the toner used to produce images by the image development system; the replenisher toner containing 20 number % or less fine particles having a particle size no greater than 5 μm.
