Abstract: The cleaning arrangement of an electrophotographic copying machine scrapes off the machine's copying drum residual toner clinging to the surface of the copying drum subsequent to image transfer, and the residual toner is conveyed generally horizontally into a toner-collection compartment. The toner-collection compartment accommodates a generally rigid but collapsible fold-up cardboard toner-collection container which is thrown away after one use. The throw-away toner-collection container, when in collapsed condition, is flat so that a sizable number of such throw-away containers can be kept on hand without requiring an inconvenient amount of storage space.

Abstract: An electrostatic copier of the type wherein an electrostatic image pattern is formed on the photoconductive surface of a travelling endless carrier, to which pattern toner particles are attracted to form a visible image which is then transferred to an image carrier, has a toner removing apparatus for removing residual toner particles from the photoconductive surface. The apparatus has a roller adjacent the surface and a doctor blade above the roller which strips toner particles from the surface so that they fall onto the roller. During rotation of the roller these particles are stripped off the roller and enter through a slot into a tube in which a polygonal cross-section member rotates which entrains the particles and conveys them to another slot of the tube to eject them from this other slot into a storage chamber.
