Toner cartridge

A toner cartridge is provided that includes an agitator provided in a toner hopper. An agitator gear is coupled with the agitator in such a way that the agitator always has the same positional relationship with the agitator gear. The agitator gear is provided with a mark indicating the orientation of the agitator and an agitation blade fixed thereto. A method of feeding toner using the toner cartridge is also provided, in which the agitator and the agitation blade are withdrawn from the vicinity of a toner feeding hole by turning the agitator gear by hand while watching this mark, and toner is refilled through the toner feeding hole. Feeding toner in this manner enables feeding a predetermined amount of toner.

The toner cartridge includes a coupling plate provided with a first support section that supports the axis of a photosensitive drum and a seconds support section that supports the axis of the magnet roller. The toner cartridge mounts this coupling plate so that the first support section supports the axis of the photosensitive drum provided in a first part of the toner cartridge and the second support section supports the axis of the magnet roller provided in the second part of the toner cartridge, thus maintaining a predetermined distance between the axis of the photosensitive drum and the axis of the magnet roller.

A communication apparatus for information comprises a recording roller for feeding a recording paper. A line-type recording head is operative for recording an image on the recording paper. Normally, the recording head presses the recording paper against the recording roller. A first releasing mechanism is operative for allowing relative movement of the recording head and the recording roller away from each other. A reading roller is operative for feeding a document sheet. A reading head is operative for reading information from the document sheet. The reading head is located near the recording head. Normally, the reading head presses the document sheet against the reading roller. A second releasing mechanism is operative for allowing relative movement of the reading head and the reading roller away from each other. First and second side plates are located respectively at opposite sides of the recording roller, the recording head, the reading roller, and the reading head. The recording head has a length smaller than a length of the reading head. The recording head is closer to the first side plate than the second side plate. The first releasing mechanism is located between the recording head and the second side plate.

Communication apparatus for transmitting and receiving information

A process cartridge case including a toner hopper, and a discharged toner box disposed at both sides of a drum housing accommodating a photoconductive drum. The process cartridge case is separable into first and second parts at a border in a region of the drum housing. Legs are provided on an outer surface of the toner hopper so that the process cartridge can be placed in an upright position during a refilling operation. An agitator extends beyond a side wall in a cantilever fashion to allow a box with a bearing member to rotatably support the agitator shaft. An elastic member is included in the box to hermetically seal the agitator shaft and prevent toner leakage.
