Abstract
In a multi-color imaging apparatus utilizing a recharge step between two image creation steps for conditioning a charge retentive surface pursuant to forming the second of the two images, a voltage sensitive corona generating device having a high characteristic slope described in a graph of the current delivered to a charge receiving surface (I) vs. grid minus charge receiving surface voltage (V) is used to both reduce the residual toner voltage across the previously toned image, and to charge the toned and untoned areas of the charge retentive surface to a substantially uniform level so that developability conditions for the subsequent image are improved.
