ABSTRACT:
An image forming apparatus includes an image carrier, an intermediate transfer element to transfer a developed image, an electrode to apply a bias having preselected polarity to the intermediate transfer element and form an electric field. The intermediate transfer element has an adhering force acting on toner of the developed image that is greater than or equal to an adhering force acting between the toner and the image carrier, and when a frictional charging polarity of the toner which rubs against the intermediate transfer element is the same polarity as the bias applied to the intermediate transfer element from the electrode.
