Abstract:
A process for producing a printed wiring board which comprises the steps of:a) exposing a wiring board having at least one photo-conductive layer in which its chargeability is changed by light exposure on at least one surface of a conductive support which comprises an insulating substrate and at least one metal conductive layer provided on at least one surface thereof through a resist pattern; b) charging the photoconductive layer to form an electrostatic latent image; c) forming a toner image on the photoconductive layer by toner developing treatment; d) removing a portion of the photoconductive layer to which no toner is attached by dissolution to form a resist image; and e) removing a portion of the metal conductive layer other than a portion where the resist image is formed by etching.
