Fuser assembly with six layer endless belt in an electrophotographic imaging device

A fuser for an electrophotographic imaging device, said fuser comprising:

• a heater assembly having a ceramic substrate;
• and
• an endless flexible belt positioned around said heater assembly, said flexible belt including:
• an inner base layer comprised of a polyimide with a thermally conductive filler;
• a metallic layer adjacent said base layer;
• a first primer layer adjacent said metallic layer;
• a thermally conductive elastic coating adjacent said first primer layer;
• a second primer layer adjacent said thermally conductive elastic coating;
• and
• an outer release layer adjacent said second primer layer.

An endless flexible belt for use in a fuser in an electrophotographic imaging device, said flexible belt having an inner diameter in an unloaded state of at least approximately 24 mm, said flexible belt comprising:

• an inner base layer comprised of a polyimide with a thermally conductive filler;
• a metallic layer adjacent said base layer;
• a first primer layer adjacent said metallic layer;
• a thermally conductive elastic coating adjacent said first primer layer;
• a second primer layer adjacent said thermally conductive elastic coating;
• and
• an outer release layer adjacent said second primer layer.
