摘要： A developer unit of the present invention has an agitating paddle which agitates a developer containing a magnetic carrier and a non-magnetic toner, and a toner is supplied from the toner hopper according to an output of a toner concentration sensor. After an agitation is finished which is performed when the power is turned on, the agitating paddle is periodically operated to agitate the developer. During the agitation, a toner concentration controller shifts a reference level with which the output of the toner concentration sensor is compared from a predetermined level to a higher level and then stepwisely returns it to the predetermined level.

摘要： An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped. When the second shutter is further pulled out after the movement of the first shutter is regulated, the seal traction opening in the second shutter tows the sealing member while allowing the insertion of the sealing member. At this time, the sealing member is stripped while being so folded that a toner adhering surface is located in its inside. In this construction, the stroke for stripping is decreased, thereby to make it possible to prevent contamination by toner as well as prevent a large part of the sealing member from being ineffective.

摘要翻译： 在含有调色剂的盒体的下部形成有用于排出调色剂的开口。 快门安装体安装在开口上。 第一挡板可滑动地安装在挡板安装体上。 第二挡板可滑动地安装在第一挡板上。 用于密封开口的密封构件的前端延伸，延伸的前端通过形成在第二闸门的前端的密封件牵引开口插入并固定到第一挡板的前端。 当第二挡板从快门安装体拉出时，密封构件被密封件牵引开口牵引。 此外，第一挡板被密封构件进一步牵引，也被拉出。 因此，从其前端的密封件的近一半被剥离。 当第一挡板的移动被调节后第二挡板进一步拉出时，第二挡板上的密封件牵引开口在允许密封构件的插入的同时牵引密封构件。 此时，密封构件被折叠，同时使调色剂粘附表面位于其内部。 在这种结构中，用于剥离的冲程减少，从而可以防止调色剂的污染以及防止大部分密封件无效。

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： 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： 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.
