Abstract
An instant-on radiant fuser apparatus for fusing toner images in an electrostatographic copying machine, which does not require the use of any standby heating devices and yet is capable of fusing the first copy in a matter of seconds. The radiant fuser apparatus is made of a low mass reflector thermally spaced from a housing, with the housing and the reflector together forming a conduit for the passage of cooling air therein. A low mass platen is provided which is constructed to achieve operating temperature conditions in a matter of a few seconds without the use of any standby heating device. A housing for the platen is also provided to form a conduit for the passage of cooling air to control the temperature of the platen.
