Abstract
There is provided with a printing apparatus. A transfer member cyclically passes a formation area and a transfer area of an ink image. A print unit forms an ink image on the transfer member by discharging ink to the transfer member in the formation area. A conveyance drum conveys a print medium and to which an ink image is transferred from the transfer member in the transfer area. A cleaning unit cleans the conveyance drum at a cleaning position where the cleaning unit contacts the conveyance drum. A displacing unit separates the cleaning unit from the cleaning position when the print medium passes the cleaning position.
