ABSTRACT:
Imaging method and apparatus utilizing some of the features of both single and two pass highlight color imaging. Both developer housings are always actively engaged. One housing is used for charged area development (CAD) and the other is used for discharged area development (DAD). The developer housing biases are switched or adjusted in order to preclude unwanted image development. When the DAD image moves through the CAD housing the CAD bias is switched to bias away the developer in the CAD developer housing. Likewise, when the CAD image moves through the DAD housing its bias will be switched to bias away the DAD developer.
