ABSTRACT:
A residual toner removing apparatus comprises a rotatable cleaning brush enclosed by a casing plate and a restriction board except for two gaps housed in a housing with an opening adjacent to a known photoreceptor surface. During rotation, brush hairs contact the casing plate to charge it with an opposite polarity to that of the toner particles, while the brush hairs are compressed by the restriction board, the cleaning brush thus acting like a fan for circulation of air and entrained toner particles, during which circulation lighter toner particles are attracted by the casing plate with heavier particles falling into catchment portions on the casing and well portions at lower parts of the housing for efficient removal of toner particles without separate vacuum means.
