The stability of corona discharge is significant in electrophotography and the other applications. It has been very known that corona discharge is affected by many factors such as silicone gases and humidity and so on. We had discussed the influence of siloxane gas in previously. In this study, we discussed the influences of temperature and relative humidity to corona discharge. The voltage for maintaining a constant corona discharge current in an atmosphere is monitored as a function of time. The applied voltage changes when the relative humidity changes in the positive corona discharge case. In the negative case, the applied voltage is changed by the temperature variation.
