Abstract
An image recording device transfers an image, which is formed on a photoconductor, onto a continuous sheet which is pressed against the photoconductor by a transfer roller. Cleaning of the transfer roller is carried out by applying a bias voltage to the transfer roller to return toner on the transfer roller toward the photoconductor. The cleaning is carried out when the transfer roller is in contact with a non-printing region of a reverse surface of the continuous sheet.
Claims14
An image recording device transferring an image, which is formed on a photoconductor, onto a continuous sheet which is pressed against the photoconductor by a transfer roller, wherein
- cleaning is carried out in which a bias voltage is applied to the transfer roller and toner on the transfer roller is returned toward the photoconductor, and
- the cleaning is carried out when the transfer roller is contacting a non-printing region of a reverse surface of the continuous sheet.
An image recording device comprising:
- a photoconductor;
- a charging unit that charges the photoconductor;
- an exposure head that exposes the photoconductor and discharges exposed portions of the photoconductor;
- a transfer roller which nips a sheet for image recording between the transfer roller and the photoconductor;
- and
- a switching portion that connects the transfer roller to one of a first bias power source and a second bias power source.
