Abstract
The Three-Level highlight color imaging, which is a one-pass process built by combinations of charged and discharged area developments, has a special problem of fringe images. The fringe image is a ghost image of the opposite color toner caused by edge effect which appears at an image edge. In this study, we examined phenomena on the fringe images. And we developed “Edge Effect Control Technology” (EECT) for avoiding fringe images. An auxiliary laser power level is exposed to the area where the fringe image is to be appeared on the photoconductor, and loosen the edge effect by avoiding dramatic potential changes on the photoconductor. Finally, Adequate conditions of EECT is revealed.
