Abstract:
An image forming apparatus comprising:an image carrying body on which a toner image is formed;transfer means for transferring the toner image formed on said image carrying body onto a transfer paper by bringing the transfer paper into contact with said image carrying body, said transfer means attracting and holding the transfer paper electrostatically, said transfer means being of a layered structure including at least a dielectric layer, a semi-conductive layer, and a conductive layer, which are laminated in such an order from a contact surface side of the transfer paper;voltage applying means, connected to said conductive layer, for applying a predetermined voltage to said conductive layer; andpotential difference generating means for pressing the transfer paper against a surface of said transfer means, and for generating a potential difference between said conductive layer, to which the predetermined voltage is applied, and the transfer paper,wherein said semi-conductive layer and said dielectric layer arc fixedly adhered to each other, andwherein said transfer means includes:a cylinder made of conductive metal, serving as said conductive layer anda one-piece sheet made of at least two layers laminated on a surface of said cylinder, each layer having a different volume resistivity,said one piece sheet being made of said dielectric layer and said semi-conductive layer, which arc laminated in such an order from a contact surface side of the transfer paper, an outer most layer of said one-piece sheet making contact with said potential difference generating means.
