Abstract
Toner particles which are removed from a photoconductive drum are trapped by a moving filter at a toner collection station and on movement of the filter to a toner discharge station, the toner is discharged into a toner reservoir. The filter may be of such a size that only the toner particles which enhance image development will be trapped thereon while the smaller toner particles will pass therethrough.
