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： A magnetic brush developing device for a xerographic copying machine is constructed to prevent toner from being leaked out of the developer housing. A magnetic brush roll is provided opposite to a photosensitive member, and at least one air current blade is provided along the lower outer periphery of the surface of the magnetic brush roll. One end of the air current blade is closely adjacent the surface of the photosensitive member, and the other end of the air current blade projects back toward the interior of the developer housing. An air circulating path is defined between the air current blade and the lower outer wall of the developer housing. This air circulating path is effective to conduct entrained air carrying excess toner back into the developer housing.
