ABSTRACT:
An electrostatic charge-removing device adapted to remove electrostatic charges formed on a light-sensitive member of a copying machine using a tungsten lamp as an erasing lamp. A filter for cutting off light of longer wavelengths is provided between the tungsten lamp and the light-sensitive member. With this device, the sensitivity of the light-sensitive member is not affected, the amount of output light does not vary with changes in the ambient temperature, and a stable amount of light is obtained over long periods of time. Moreover, the lamp can be started instantaneously without the use of a special circuit.
