A developing system is provided for a copying process such as an electrophotographic copying process in which a developer is supplied to the surface of a member which is formed with an electrostatic latent image to provide developing thereof. An electrode is disposed opposite the surface of the member with the developer interposed therebetween, and the induction potential of the electrode is maintained below a given value by means of a constant voltage element. The potential of the electrode is induced by either the image portion of the member's surface having the electrostatic latent image or by an unexposed, separate charged portion thereof.
