Patent ID: 8289003

Claim:
A discharge apparatus comprising: a discharge device having a temperature characteristic in which impedance of the discharge device in a discharging state decreases as ambient temperature of the discharge device increases; a capacitor that stores charge for causing the discharge device to discharge; a discharge control device that controls electrical connection and disconnection between the capacitor and the discharge device; and a current limiting device that limits a current flowing in the discharge control device to a predetermined value or less when the discharge control device electrically connects the capacitor to the discharge device, the current limiting device being serially connected to the discharge device, the capacitor, and the discharge control device, such that the current limiting device is provided between the discharge control device and one end of the discharge device, and the capacitor is provided between the discharge control device and an other end of the discharge device, wherein the current limiting device is a thermistor having a temperature characteristic in which resistance of the thermistor increases as temperature of the thermistor increases.
