Abstract:
A transfer roller includes a conductive support, a first conductive elastic layer disposed on the conductive support, and a second conductive elastic layer disposed on the first conductive elastic layer. A common logarithm of surface resistivity of the second conductive elastic layer is higher than a common logarithm of volume resistivity of the second conductive elastic layer by about 1 or more.
