Abstract
Some theoretical analyses are given on the corona charging characteristics of an ideal sample having a homogeneous structure and a infinite leakage resistance, and various fundamental formulas obtained by the above analyses are listed in a table. Some discussions are also made about the effects of sample parameters such as donor density, dielectric constant and thickness on the Q-V curves of samples
Using a turn-table type equipment, measurements were made on the variations of surface potential V and electric charge Q during the process of corona charging of various kinds of ZnO binder layers and commercial electrophotographic paper. The values of layer parameters such as effective donor density, dielectric constant and avalanche starting field strength have been determined from the comparison between theoretical and experimetal Q-V curves.
