A cleaning apparatus is disclosed which removes residual toner particles from a photoconductor by use of magnetic carrier particles. The carrier particles form magnetic brushes which adsorb and thereby remove the residual toner particles from the photoconductor. Two relay sleeves each having permanent magnets thereinside cause the removed toner particles to circulate together with the carrier particles. A toner collector roller and a counter electrode face each other at opposite sides of a circulation path for the carrier particles which are carrying the toner particles therewith. The toner collector roller collects the toner particles adsorbed by the carrier particles. The counter electrode comprises a relatively narrow and grounded conductive electrode portion and a relatively wide insulator portion.
