Abstract
An imaging system includes a transfer belt that is rotatable, a transfer roller that contacts the transfer belt, and a conductive device that contacts a surface of the transfer roller, to supply a bias to the transfer roller. The transfer roller has a hollow portion.
Claims15
An imaging system comprising:
- a transfer belt;
- a driving roller to rotate, wherein the driving roller engages the transfer belt to move the transfer belt;
- a transfer roller located adjacent the driving roller, wherein the transfer belt is interposed between the transfer roller and the driving roller to form a transfer nip portion between the transfer roller and the transfer belt, and wherein the transfer roller includes a hollow portion to cause the transfer roller to deform when subjected to an external force;
- a conductive device to contact a surface of the transfer roller;
- and
- a power source electrically connected to the conductive device, to supply a bias to the transfer roller through the conductive device.
