    Abstract: Electrostatographic apparatus including transfer means (7, 8, 42) for transferring a developed electrostatic latent image from an imaging surface (1) onto a copy sheet, the transfer means comprising a transfer corotron (7), a de-tack corotron (8) and a halo guide (42). The halo guide includes a halo limiting portion (43) adjacent the transfer corotron (7) and a copy sheet guide portion (44) for guiding the sheet onto the imaging surface. The copy sheet guide portion (44) carries an electrically biassed member, and by virtue of its contacting the copy sheet, maintains it at a potential suitable for efficient transfer of the developed image regardless of the electrical conductivity of the copy sheet. The biassed member may be provided by a thin metal plate (45) secured to the guide portion (44) by means of an insulating layer (46) such as a double sided adhesive tape.

    Abstract: A xerographic cassette (10) for a printing or copying machine includes a photoreceptor drum (11), a cleaning blade (15), and waste toner conveying means (20, 22, 23) for conveying waste toner cleaned off the photoreceptor drum by the cleaning blade, into the interior (21) of the photoreceptor drum for storage. The conveying means includes a flexible helical wire (20) which acts as an auger. A curved tube portion (23) of the conveying means passes through an auxiliary waste toner container (30), the tube being perforated to release toner into the auxiliary waste toner container. Once the auxiliary container is substantially full, waste toner is conveyed into the interior (21) of the photoreceptor drum. The auxiliary container (30) is provided with access means (38) to enable it to be emptied, thereby prolonging the useful life of the cassette. When the drum interior (21) and auxiliary container (30) are both full, waste toner builds up in container housing (16) which eventually activates switch (42) on top of the housing sending out a "replace cassette" signal.
