摘要： A device for use in an electrophotographic duplicator employing a sensitive member comprising a temperature-dependent sensitive material whose static charge characteristic varies with the surface temperature thereof, the sensitive member bearing an electrostatic latent image having an image region and a background region, the device comprising a developing electrode disposed at the periphery of the sensitive member for effecting uniform development of the image region; temperature sensitive means disposed in the vicinity of the sensitive member responsive to the surface temperature of the sensitive member for generating a bias potential for the developing electrode, the developing electrode being so controlled by the bias potential that the bias potential is always maintained at a value greater than the value of the potential of the background region even when the temperature at the surface of the sensitive material decreases substantially thereby necessitating a substantial increase in the bias potential whereby little, or any, toner is deposited on the background region to thereby lessen fogging thereof.

摘要： 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.
