Abstract
Cleaning roller (7) contacts intermediate transfer roller (4), each rotating at the same surface speed to avoid rubbing. The cleaning roller has an electric potential sufficient to remove toner from the transfer roller to clean it. Silicone oil is applied by a roller 29, which is wetted by oil from a oil impregnated wiper (31). The oil facilitates cleaning and reduces wear of the intermediate transfer roller, which is typically soft to facilitate transfer.
