Abstract
An ink jet head unit is provided above a rotating intermediate transfer device such that nozzle surfaces face to the intermediate transfer device. A release oil jet head and a blade are provided on the upstream side of the ink jet head unit relative to the direction of rotation. Fine oil is ejected from the release oil jet head onto the intermediate transfer device and the fine oil is smoothed using a tip of the blade. Since the release oil is ejected using the ink jet method, the most suitable thickness of release oil film can be formed by controlling the area and the amount of the application. As a result, evenly transferred high quality images can be obtained.
