ABSTRACT:
A cleaning device for an electrostatic copier of the type having an endless travelling charge carrier provided with a photosensitive surface which is electrostatically chargeable to form a latent image to which toner particles are attracted for subsequent transfer to an image carrier. The cleaning arrangement removes residual toner particles from the surface prior to the next electrostatic charging thereof and is in form of a cleaning cartridge that can be inserted into and removed from the copier in toto. The cartridge has a leading open end and instrumentalities at this end which engage the photosensitive surface of the charge carrier when the cartridge is inserted into the copier. Elastically deformable sealing elements are provided on the cartridge and at least in part bound the open end thereof, yieldingly engaging the photosensitive surface in response to the insertion of the cartridge into the copier.
