Abstract
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.
