Abstract:
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.

Claim (Index 1):
An image forming apparatus comprising:\n a conveyance section that conveys a sheet; an image forming section that includes an image carrier and forms a toner image on a surface of the image carrier; a fixing section that nips, at a fixing nip between two rotating bodies, the sheet having the toner image formed in the image forming section and applies heat and pressure to the nipped sheet to fix the toner image on the sheet; a sheet output tray to which the sheet having the toner image fixed thereon by the fixing section is discharged; a toner container that is removably loadable in an apparatus body of the image forming apparatus and contains toner for use in forming the toner image in the image forming section; a suitable product determining section that determines whether or not the toner container loaded in the apparatus body is a suitable product; and a control section that controls operations of the conveyance section, the image forming section, and the fixing section, wherein the image forming section includes a developing device that supplies to the image carrier the toner supplied from the toner container and forms the toner image on the image carrier, wherein when the suitable product determining section determines that the toner container loaded in the apparatus body is not a suitable product, after every predetermined number of sheets have been subjected to an image forming operation or when every predetermined term has passed, the control section controls the conveyance section, the image forming section, and the fixing section to allow formation of a solid image having a predetermined length on the sheet and to pass the sheet on which the solid image is formed through the fixing nip, to thereby allow a cleaning operation of removing a contamination adhering to surfaces of the rotating bodies of the fixing section to be performed, and wherein the predetermined length is set to be equal to or longer than a circumferential length of one of the rotating bodies coming into contact with the solid image.
