ABSTRACT:
A method whereby a large number of copies can be produced from a single electrostatic latent image formed on one of a dielectric member, an insulating member or photoconductive member by developing and printing the image by transfer printing in successive operations. The absolute value of a bias voltage impressed on the developing device in developing the electrostatic latent image is gradually reduced until the number of copies produced reaches a specific level, and then progressively increased as the number of copies produced increases for producing copies in numbers which exceed the specific level, whereby copies of a number greater than the number of the specific level can be produced from the same electrostatic latent image.
