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.

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 deviceincludes a control memberfor controlling an amount of a developer supplied to an image bearing memberby causing a developer captured on a surface of a developing sleeveto be uniform in layer thickness. The control memberis arranged to face, via the developing sleeve, one () of a plurality of magnetic poles provided inside the developing sleeve. Further, the control memberis arranged to be in parallel with a developing rollerin an axial direction of a magnet fixing shaft. The control memberis such a non-magnetic member that the nearest part of the non-magnetic member from the developing rollerhas been caused to be ferromagnetic and has been magnetic-field oriented.

Developing device and image forming apparatus including the developing device

A developing device and an image forming apparatus capable of suppressing occurrence of development hysteresis and moving a developer on a chute without being retained is provided. The developing device provides a chute that guides a two-component developer regulated by a regulating member in the direction separating from a developing roller. The chute is composed of a rectangular thin plate made of non-magnetic austenitic stainless alloy, and a tip part that is one end part in a short side direction thereof is provided so as to face a surface of the developing roller. The tip part is transformed to a processed induced martensitic phase to be made ferromagnetic, and subjected to magnetic field orientation in an area facing the surface of the developing roller so as to form a repulsive magnetic field.

A developing device for an image forming apparatus includes a partition member for partitioning an internal space of the developing device into a first carrying and second carrying paths, and a sliding member provided adjacent a developing roller and having an inclined planar surface. Residual developer collected from a surface of the developing roller slides along the inclined planar surface of the sliding member toward the first carrying path P, and the developer hits an inclined carrying surface of the partition member. A first portion of the developer slides along the carrying surface of the partition member and falls into the second carrying path. An opening in the carrying surface of the partition member allows a second portion of the developer to pass through the partition member and into the first carrying path.

A developing device is disclosed which includes a developing tank, a developing roller, a carrying member, and a filter. Rotation of the developing roller causes a first airflow directed from the outside of the developing tank through an air path to the inside of the developing tank. Rotation of the carrying member causes a second airflow directed from below in an upward direction inside the developing tank. Collision between the first airflow and the second airflow causes a third airflow directed from the inside of the developing tank through the filter to the outside of the developing tank and further from the outside through the filter back to the inside of the developing tank. This arrangement prevents not only filter clogging but also a toner leak to the outside of the developing device.

A toner stirring section provided in a toner cartridge includes a first rotating body and a second rotating body. The first rotating body is rotated around an axis Jto stir a toner. The second rotating body includes a conveying sheet for conveying the toner to a toner replenishing roller which is a conveying destination, to be rotatably provided around the axis J, and to rotate by being pressed by the first rotating body being rotated. The first rotating body and the second rotating body are provided so that the first rotating body presses the second rotating body after the first rotating body is rotated by a predetermined degrees relative to the second rotating body.
