Estimating the term…
Toner collecting apparatus in which a toner collecting container for collecting toner remaining on the surface of a photosensitive drum in a copying machine or a facsimile machine is provided, at the lower side thereof, with a toner receiving port, a sponge roller for rotatingly feeding collected tone disposed adjacent the toner receiving port, and an optical detector for detecting that a predetermined amount or more toner has been collected in the toner collecting container. The optical detector, is disposed on the toner collecting container. At least those portions of the toner collecting container located opposite to the optical detector are made of a light-permeable material.
Toner collecting apparatus comprising a photosensitive drum for forming a latent electrostatic image, a cleaning blade for removing toner remaining on the surface of said photosensitive drum, a seal blade for guiding toner removed by said cleaning blade, a toner collecting container having a toner receiving port formed at a predetermined position in a lower side of said container for collecting removed toner therein through said port, a toner feeding member being constructed of a porous material and being located adjacent said toner receiving port for feeding collected toner, said toner feeding member being in continuous pressure contact with an upper edge of said toner receiving port and located adjacent a lower edge of said port and being rotatingly driven in a direction from said lower edge of said toner receiving port to said upper edge thereof, and an optical detector disposed on said toner collecting container, said container having portions made of light-permeable material located in opposition to said optical detector.
