Abstract

PURPOSE: To make possible dichromatic copying of two-color originals simply through one time of exposure and two times of development by so forming the latent image that the potentials VI, VII of the portions for the impage part by the potential V0 for the texture part become VII > VI > v0 and vary mutaully stepwise.
