Abstract
The invention provides a toner supply and cleaning roller that secures sufficient density especially at an initial stage of printing, and an image forming apparatus using the same. The toner supply and cleaning roller has a shaft () and an electroconductive elastic layer () made of a urethane foam and supported on the circumference of the shaft () by means of an adhesive layer () in between. The resistance of the roller at an applied voltage of 100 V is 10Ω or lower, preferably 10Ω or lower, and the resistance of the roller at an applied voltage of 5 V is 10to 10Ω. The adhesive layer () contains a hot-melting polymeric adhesive and is formed preferably at a temperature not exceeding the melting point of the hot-melting polymeric adhesive.
