A toner cartridge includes a screw configured to send stirred toner to an outlet through which the toner is discharged. The toner cartridge includes a partition between the screw and a toner stirrer. The toner stirrer at a default position is in contact with a top of the partition and covers the screw from above to define a closed space around the screw. The closed space is separate from a remaining space having the toner therein. The closed space is in communication with the remaining space when the toner stirrer rotates from the default position to be away from the toner transport screw, enabling the toner to move toward the toner transport screw.

When a device desired to acquire emission right information is selected on a selection screen displayed on a display unit and a 'SEND' icon is manipulated, a control unit causes the display unit to display consumables information of consumables granted with emission rights and consumables not granted with emission rights that is received from a server. When a user selects a consumable item that is desired to be ordered from among consumables indicated by the consumables information displayed on the display unit, and manipulates a 'SEND ORDER SHEET' icon on the ordering screen, the control unit sends an order sheet to the server. The control unit causes the display unit to display, in the case of receiving order sheet receipt notification from the server in response to the sent order sheet, the received order sheet receipt notification.

A charging roller has a conductive shaft, a charge emission member provided to the shaft, and a gap securing member provided to the shaft. The gap securing member (i) protrudes toward the photoreceptor drum so as to be closer to the photoreceptor drum than the charge emission member is to the photoreceptor drum and (ii) is in contact with the photoreceptor drum so as to secure a gap between the charge emission member and the photoreceptor drum. A conductive part of the gap securing member and the shaft are bonded to each other by electrically releasing adhesive, so that the gap securing member is provided to the shaft.

An image forming apparatus including an operation panel has, as a configuration of the operation panel, a display portion including a function to display environmental label information of the image forming apparatus. The environmental label information includes information on a type of greenhouse effect gases (CO) and a total emission amount of the greenhouse effect gases in a life cycle of the image forming apparatus. On the display portion, there is provided a selective display portion for displaying an environmental label as list display or thumbnail display, as well as selectively displaying detailed information of the environmental label according to the environmental label.

Image forming apparatus including display device

The image forming apparatus of the present invention includes an image forming main device which has a control section. The control section (a) obtains, from an external device via a communication device, option information indicative of an at least one optional device and eco-information indicative of an amount of greenhouse-gas emitted due to the at least one optional device, (b) controls a display device to display the option information and the eco-information, and (c) sends, to the external device via the communication device, an order for an optional device selected by a user via the input device out of the at least one optional device indicated by the option information displayed on the display device.

A developing device includes a developer reservoir having developer stored therein, a developing roller for carrying developer, a sealing member which is brought into close contact with the developer portion so as to cover a communication port in communication with inside of the developer reservoir, and a sealing passing member for passing the sealing member peeled off the developer reservoir, wherein the sealing member is peeled off the developer reservoir to open the communication port and the sealing passing member has an opening with an approximately elliptical shape, through which the sealing member passes.

Image forming apparatus

A toner cartridge is provided removably fitted to a toner supply pipe for supplying toner to a developing device. The toner cartridge includes, as a toner discharging mechanism, a toner discharging portion having a toner discharge port, a toner conveyor screw for conveying toner inside toner container and a shutter for opening and closing the toner discharge port. The shutter has a loosening member. When the toner cartridge is fitted to the toner supply pipe, the loosening member moves inside the toner container as the shutter moves along the toner discharge port.

A communication unit has a first conveyance part connected to a toner cartridge and provided with a feed port for a toner from the toner cartridge, and a second conveyance part connected to a developing device and provided with a replenishment port for a toner to the developing device. In a state locked by the lock mechanism, the first conveyance part and the second conveyance part are connected to each other, and the feed port of the first conveyance part and the replenishment port of the second conveyance part are opened, allowing for a toner replenishment. In a lock-released state, the feed port of the first conveyance part and the replenishment port of the second conveyance part are closed by a circular arc-shaped shutter member and a rotary shutter member, allowing the first conveyance part and the second conveyance part to be separable from each other.
