摘要： A toner recovery roller having at least its outer peripheral part made of an insulator and rotated and driven in a predetermined direction is disposed in the vicinity of a position where an image carrier and a developing roller interact with each other, and a triboelectric charging member for triboelectrically charging an outer peripheral surface of the toner recovery roller to a polarity opposite to that of toner particles is so provided as to be brought into contact with the outer peripheral surface of the toner recovery roller.The rotation of the toner recovery roller in a predetermined direction causes friction between the friction charging member and the insulating outer peripheral surface of the toner recovery roller, so that the insulating outer peripheral surface of the toner recovery roller is triboelectrically charged to a polarity opposite to that of toner particles. Therefore, toner particles scattered from the developing roller are attracted to the toner recovery roller to adhere thereto.A charging potential of the toner recovery roller does not immediately reach zero but remains to some extent even in cases, for example, immediately after a copying machine is stopped, when the power supply of the copying machine is turned off immediately after copying is terminated, and when a front door of the copying machine is opened by paper jamming or the like. Also in this case, therefore, floating toner particles are attracted to the toner recovery roller to adhere thereto.

摘要： An image forming apparatus which facilitates the input and output of copy paper. One embodiment includes an image forming apparatus with paper supply trays, a development area, a console and a sorter. By pressing a transparent paper mode key on the console, normal and projector paper are sequentially fed from the trays to the development area and then to the sorter. The sorter is set in one of three modes by a sorter instructor. A manual key on the console allows an operator to set the instructor to position the sorter in any one of the three modes. The pressing of the transparent paper mode key or the detection by a detector of transparent paper in the feeding tray results in the instructor setting the sorter in a non-sort mode despite the sort instructor having been previously set in a different mode. Also, another embodiment of the invention includes a judging device for judging whether a cover copy mode or a page numbering mode has been inputted to the copying assembly and, if so, then the sorter instructor sets the sorter in a sort mode. Another embodiment uses a selecting device to match the detected size and orientation of the transparent paper with a similar detected size in one of a plurality of cassettes containing non-transparent paper. An additional embodiment features rear and face discharging modes which, when set, result in a predetermined positioning and sequencing of the transparent projector and normal paper.

摘要： An electrostatic latent image-developing device is equipped with a toner cartridge-holding means and a toner cartridge fitted thereto. The toner cartridge includes a container with a toner discharge openings, a toner contained in the container, and a sealing means for sealing the toner discharge opening. The sealing means is constituted by a tape member that is provided to move across the toner discharge opening, and a toner passage opening is formed in the tape member. The toner discharge opening is opened when the tape member is so moved that the toner passage opening is positioned at the toner discharge opening. The toner cartridge-holding means includes a hoist frame that moves up and down, and the toner cartridge is held in this hoist frame.

摘要： When documents fed by an automatic document feeder are subjected to the first copying operation, the documents are counted one by one. Alternately, the total number of documents are calculated by dividing the number of copy paper sheets sent to an intermediate tray, by the preset number of copies. Page entry is made in the copy paper sheets taken out from the intermediate tray, based on the total number of documents thus obtained. The total number of documents may be automatically counted. Accordingly, even though the documents are successively fed, starting from the last-page document, page entry may be made. The operator is not required to manually count the total number of documents.

The cleaning means includes a cylindrical brush formed of a multiplicity of radially extending yarns. The brush of the cleaning means is mounted rotatably about the central axis of rotation extending substantially parallel to the central axis of rotation of the rotating drum, is pressed against the photosensitive material, and is caused to rotate following the rotation of the rotating drum.

摘要： A toner transport device includes a toner transport path for passing toner, and a toner transport pipe disposed so as to have an up-and-down direction in which the toner transport path extends. Further, the toner transport device includes a pipe supporting member for supporting the toner transport pipe, which is supported so as to move up and down. This allows the toner transport pipe to vibrate up and down, thereby properly preventing retention and solidification of toner inside the toner transport path.
