Image transfer device with cleaner for electrophotographic copying

摘要

An image-transferring system which may be employed in an electrophotographic type of copying machine. The image-transferring system includes an image transfer member on which a toner image is formed, a transfer roller arranged to hold a transfer paper along with the image transfer member to transfer the toner image formed on the image transfer member onto the transfer paper, a cleaner arranged to clean a surface of the transfer roller before the image-transferring operation, and a cleaner supporting member which is designed to support the cleaner for controlling a cleaning operation of the cleaner with given timing where the cleaner engages the transfer roller in response to engagement motion of the transfer roller with the image transfer member.
