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： 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, the control section allows the conveyance section, the image forming section, and the fixing section to form, on a sheet, a solid image having a circumferential length of one of rotating bodies of the fixing section or longer, and allows the sheet on which the solid image is formed to pass through a fixing nip, to thereby periodically allow a cleaning operation of removing a contamination adhering to surfaces of rotating bodies of the fixing section to be performed.
