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.
