Single positive recharge method and apparatus for color image formation

摘要

In a multi-color imaging apparatus utilizing a recharge step between two image creation steps, a corona generating device is used to recharge the developed image areas and untoned areas of a charge retentive surface to a lower electrical potential than that associated with the developed image areas before recharge, so that the residual voltage associated with the developed image is substantially reduced and a minimal level of negative charge is driven through the toner layer(s). An electrical charge associated with any previously developed images is substantially neutralized prior to development of any subsequent images thereon.
