The purpose of this paper is to analyze re-transfer phenomenon of corona separation. We have tried to clarify some characteristics of this phenomenon in terms of energy-analysis, which was applied to the analysis on the mechanism of corona separation by the authors. Consequently we have found that the range of discharger conditions, on which corona separation is possible, could be divided into the maximum 3 regions on re-transfer phenomenon.
1) The first is re-transfer region, on which this phenomenon is always generated to all image density.
2) The second is neutral region, on which this phenomena is or not generated by image density.
3) The third is non re-transfer region, on which this phenomenon is not generated to all image density.
As separation efficiency grows bigger, neutral region, re-transfer region and non re-transfer region appear in that order.
In order to verify these facts, we had an experiment with the laser printer and we could get good results which agree with the theoretical analysis roughly.
