ABSTRACT:
Apparatus for collecting charged toner particles suspended in an air flow is provided. The present apparatus is particularly useful when used in combination with a fur brush cleaning device of a transfer type electrophotographic copying machine. The present collection apparatus comprises a roller electrode and a counter electrode disposed opposite to the peripheral surface of the roller electrode. A blade is provided in contact with the roller electrode. The roller electrode includes an insulating section which always keeps in contact with a portion of the blade thereby roller and counter electrodes are prevented from being bridged by deposited toner particles. A disposable filter unit may be advantageously mounted on the collection apparatus.
