Abstract:
Printing methods are provided. A surface charge is provided on the primary imaging member and the surface charge is partially discharged in areas in which a first toner is to develop. The charge pattern is formed with a first area having a surface potential that is at least 30 percent less than a surface potential of an adjacent second area that creates an inter-area field between the first area and second area that extends into a portion of the first area that is proximate to the second area. A first development field is applied and a first toner is partially developed in the first area based upon the influence of the inter-area and first development fields. The charge pattern and the first toner are further developed with a different second toner. The surface charge on the primary imaging member, first toner and second toner have the same polarity.
