    摘要: An image forming apparatus includes a conveyance section, an image forming section, a fixing section, a sheet output tray, a toner container, a suitable product determining section, and a control section. The suitable product determining section determines whether the toner container loaded in an apparatus body is a suitable product. When the suitable product determining section determines that the toner container is not a suitable product, on condition of successive feeding of sheets, the control section allows, after every predetermined number of sheets have been subjected to an image forming operation, a fixing aging operation for stopping the image forming operation and rotating rotating bodies of the fixing section to be performed. When the suitable product determining section determines that the toner container is a suitable product, the control section keeps the fixing aging operation conditional on successive feeding of sheets from being performed.

    摘要: An image forming apparatus includes a transport unit, an image forming unit, an output tray, a toner container, and a processor that realizes a function of a conformity decision unit, a change reception unit, and a controller. The controller discharges, when the conformity decision unit decides that the toner container is not a conforming product, a quality check sheet to the output tray each time a predetermined number of sheets have been printed, or each time a predetermined time has elapsed. The change reception unit receives a change of a quality adjustment value from a user. The controller controls the operation of the transport unit and the image forming unit, according to the quality adjustment value that has been changed and received by the change reception unit.

    摘要: A developing device includes a developing container, a first agitating/conveying member, a second agitating/conveying member, a developer supply member, a supply port, and a supply section. The developing container is separated into a developer supply passage, a first conveying chamber, and a second conveying chamber, which are arranged substantially parallel to one another. The supply section is disposed between the developer supply passage and the first conveying chamber, and through the supply section, the developer is supplied from the developer supply passage into the first conveying chamber. The supply section is disposed upstream from a downstream-side end portion of the developer supply passage but downstream from the supply port with respect to a developer-conveying direction of the developer supply passage, and via the supply section, the developer supply member supplies the developer into the first conveying chamber in a direction opposite to a developer-conveying direction of the first conveying chamber.

    摘要: A developing device includes a housing, a developer carrier, a conveying member and a surface layer. The conveying member conveys the developer in the first conveying direction and supplies the developer to the developer carrier. The surface layer is arranged on the circumferential surface of the developer carrier and formed on a surface of a predetermined cylindrical base member. The surface layer is formed by an immersion method of immersing the base member in an immersion tank so that an axial direction of the base member extends along a vertical direction. A lower end side of the base member at the time of the immersion is arranged in a downstream side of the housing in the first conveying direction and an upper end side of the base member at the time of the immersion is arranged in an upstream side of the housing in the first conveying direction.
