Transfer device

In a transfer device for transferring a toner image formed on the surface of an image forming body to a copy medium, of the type comprising a rotatable transfer roller facing the image forming body and pressing the copying medium to the surface of the image forming body, the improvement comprising:

• providing said transfer roller with elasticity to elastically press the copying medium to the surface of the image forming body thereby contacting with wider area, said transfer roller including a core provided with an outer circumferential surface and having a cylindrical rigid core bar and an elastic layer formed coaxially with said core bore on the outer circumferential surface thereof, an elastic and electrically conductive layer formed of an electrically conductive adhesive agent applied to said outer circumferential surface of said core, and a great number of electrically conductive furs electrostatically planted in said electrically conductive adhesive agent and projecting from the outer circumferential surface of said electrically conductive layer, said core bar having electrical conductivity and axially protruding from the end faces of said elastic layer, and said electrically conductive adhesive agent being a continuous layer applied to the outer circumferential surface of said core and part of said core bar;
• and
• a bias power source connected to said core bar for charging said copying medium.
