  • Patent number: 9152967
    Abstract: 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.

  • Patent number: 8699926
    Abstract: A developing device 2 includes a control member 116 for controlling an amount of a developer supplied to an image bearing member 3 by causing a developer captured on a surface of a developing sleeve 119 to be uniform in layer thickness. The control member 116 is arranged to face, via the developing sleeve 119, one (120b) of a plurality of magnetic poles provided inside the developing sleeve 119. Further, the control member 116 is arranged to be in parallel with a developing roller 114 in an axial direction of a magnet fixing shaft 126. The control member 116 is such a non-magnetic member that the nearest part of the non-magnetic member from the developing roller 114 has been caused to be ferromagnetic and has been magnetic-field oriented.

  • Patent number: 8615187
    Abstract: 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.

  • Patent number: 8600268
    Abstract: 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.

  • Patent number: 8406650
    Abstract: 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.
