ABSTRACT:
In a process for reproducing images of fine lines of characters of low density, the latent image is initially transferred onto transfer paper such that charges, including the non-image portions of the original, are transferred onto substantially the entire area of the transfer paper so as to assure transfer of fine images and subsequently developing the transfer paper by a wet-type developing technique such that the transfer paper is passed through at least one electrode effective region having a greater potential than the potential of the non-image portion and a polarity the same as the potential of the areal image of the non-image portions, and also passing the transfer paper through at least one electrode non-effective region to clearly visualize only the latent image with the images of low densities.
