Abstract
Apparatus for recovering waste toner in a copier or printer includes a rotatable heating drum and a heat source for heating the drum so that its exterior surface reaches a temperature sufficient to melt toner particles. Waste toner particles that are removed by a cleaning apparatus are fed through a chute onto the surface of the heating drum for melting. A rotatable receiving roller forms a transfer nip with the heating drum for transfer receiving melted toner from the heating drum. Melted toner on the receiving roller is cooled off into a solid mass or plug of toner for clean, safe disposal.
