Corona charging characteristics of photoreceptor is influenced by pre-exposure. The information of traps is obtained from the change of the charging characteristics by pre-exposure. In this report, the information of traps is analyzed by measuring on OPC (organic photo conductor) with three different thickness of photo generation layer. It is also reported the computer calculation method of the absorption current in OPC from the values of sampled surface voltage.
