Abstract
Fusing apparatus for an electrographic printer, includes an abhesive belt for carrying and contacting a recorded image, a low temperature heater to fuse the image, and an assembly for synchronously moving a sheet in contact with the belt past the heater for an extended dwell time so that the toned image attains a fusing temperature as it resides in thermal contact with the heater along an extended transport path. The belt has a release coating of low surface free energy. Image transfer or fusing may be accomplished at sufficiently low belt temperatures that a single belt may be employed to effect imaging, toning, image transfer and fusing steps without impairing heat-sensitive toning assemblies, photoconducting elements, or other temperature-sensitive parts of the printer.
