PROBLEM TO BE SOLVED: To perform excellent development by using a resin made supporting body and surely neutralizing counter charge to accompany the toner development. SOLUTION: A printing electrophotographic original paper is formed by laminating a conductive layer 5 and a photoconductive layer 7 on the resin made supporting body 3 and an electrode part 5a electrically connected to the conductive layer 5 is formed on the side surface in the width direction. At the time of development, the electrode part 5a is brought into contact with a supporting body side electrode 11 and the potential of the conductive layer 5 is made equal to that of the supporting body side electrode 11. An electrostatic charge latent image is surely and rapidly neutralized by the counter charge with the toner development and an excellent image is developed in spite of using the resin made supporting body excellent in flatness. In a developing device, a stainless made roller, a conductive brush or the like is installed as a structure to ground the electrode part 5a.
