Instant start fusing apparatus

Apparatus of the type which fuses toner images onto support material by heat and pressure including an instantly heated fuser roll and a pressure back-up roll having an elastomeric surface. The fuser roll has a cylindrical member made of quartz or other material which transmits radiant energy from a source located on the interior of the cylindrical member. The cylindrical member has a first layer made of elastomeric material which transmits radiant energy. The first layer is covered with a second layer of material which absorbs radiant energy. A third layer of material covers the second layer of heat absorbing material to effect a good toner release characteristic on the fuser roll surface. The third or image contacting layer may be made of an elastomeric material where dry fusing is preferred or alternatively a rigid material where a silicone oil is applied to the image contact layer to prevent toner offset onto the fuser roll surface. The fuser roll layers are relatively thin and have an instant start capability to fuse toner images onto support material, such as paper.
