摘要： A transfer device includes an endless belt, an external roller, and an internal roller. The external roller is arranged outside of the loop of the endless belt and the inner roller is arranged inside of the loop of the endless belt. The endless belt is sandwiched between the external roller and the internal roller. A surface hardness of the external roller and a surface hardness of the internal roller are 50 degrees or more in an asker C scale. A logarithm (LogR) of volume resistivity of the intermediate transfer member is 10.0 or less.

摘要： An image forming apparatus of the present invention includes an intermediate image transfer belt passed over a plurality of support members and movable while carrying a toner image of preselected polarity transferred thereto. An electrode member contacts the inside surface of the belt and is applied with a preselected voltage for transferring the toner image from the belt to a recording medium. A contact member with high electric resistance contacts the belt at a position adjacent the electrode member and includes an insulating layer thereon.
