Disclosed is a waste toner system and method that improves densification or compaction of waste toner particles thereby reducing: the volume of waste, the frequency of waste removal and servicing, and the size of the waster toner receptacle. The system is comprised of existing waste toner collection hardware and additionally a heating means is provided to warm the waste toner recepticle to about the glass transition temperature of the waste toner. Continuous or programmed periodic heating causes the waste toner to flow and fuse resulting in a solid toner mass which has few or no free toner particulates. The waste toner thermal treatment process may be used within an operating xerographic machine or may be used following removal of the waste recepticle from the machine.
