ABSTRACT:
A cleaning device for an electrophotographic copying machine includes a blade mounted on a housing so as to scrape off a residual toner from the surface of a photosensitive member. A seal member is mounted on the housing so as to guide the scraped-off toner into the housing to collect the toner in the housing. A rotary screw discharges the collected toner from the housing. A vibrating member is mounted on the housing and disposed adjacent to and inwardly of the seal member. The vibrating member includes a plate-like portion having an edge portion contacted with the rotary screws, and is adapted to be vibrated during rotation of the rotary screw. The plate-like portion is formed with a number of slits spaced apart from each other by a distance smaller than a pitch of the rotary screw, so as to enable to effectively vibrate the plate-like portion of the vibrating member.
