Abstract: A portion of a xerographic development material is slowly circulated past a vertically oriented porous wall where it serves as a filter for airborne toner particles flowing therethrough. Toner enriched development material is returned to the main body of development material for reuse. Toner particles cleaned from residual xerographic images are conveniently transported by airflow entrainment to the development material filter.
