Title: Method and apparatus of developing electrophotographic master plate for printing

Abstract: A conductive layer 5 and a photoconductive layer 7 are laminated on a support member 3 made of resin so that an electrophotographic master plate for printing is constituted. Electrode portions 5a electrically connected to the conductive layer 5 are formed on the widthwise directional side surfaces. When development is performed, the electrode portions 5a are brought into contact with an electrode 11 adjacent to the support member 3 so that the potential of the conductive layer 5 is made to be the same as the potential of the electrode 11 adjacent to the support member 3 though the electrode portions 5a. The developing apparatus has a structure for causing the electrode portions 5a to be grounded by a provided roller made of stainless steel and/or a conductive brush.
