Abstract

A printer or copier which operates by transfer printing has a fixing roller for affixing toner to the recording medium. A release agent, or parting oil, is applied to the roller by a dosing tube having openings through which the release agent flows to a wick. An application element is moved over the roller between the wick and the roller for cleaning and application of the release agent. The wick is held in guide elements and the lower guide element has a duct for collecting excess release agent and applying it to the application element.
