Abstract
An image forming apparatus for forming images on a media substrate having an electrophotographic image forming apparatus including apparatus for selectively applying a toner release agent. The apparatus includes a supply roller for applying a toner release agent onto a fuser roller or other roller. In operation, the supply roller is selectively moveable by a thermally-activated actuator such as a pair of shape memory alloy (SMA) members from a first position where the supply roller engages the fuser roller and communicates the toner release agent thereto, and a second or disengaged position where supply roller does not contact the fuser roller. A method for applying a toner release agent in an electrophotographic imaging forming apparatus, and a method for printing toner images on a substrate such that all of the toner images adhere to the substrate are also disclosed.
