Abstract:
1. An image forming apparatus that includes a first image forming device that includes a second image forming device that includes a belt member that carries the recording medium thereon to both the secondary transfer position and a direct transfer position at which the second toner image is transferred from the second image carrier onto the recording medium, the belt member being rotatably supported by a plurality of roller members, the image forming apparatus comprising: a lubricant applying unit that applies a lubricant to at least one of the first image forming unit and the second image forming unit; a toner-image detecting unit that faces an outer surface of the belt member and detects any toner image on the belt member; a cleaning member that is in contact with the outer surface of the belt member and removes toner from the outer surface of the belt member; an image adjusting unit that forms a test pattern on the belt member by using the first image forming device and the second image forming device, detects the test pattern by using the toner-image detecting unit, and adjusts, in accordance with a result of the detection, an image forming condition of each image forming unit; and a toner input unit that applies toner to the belt member, thereby inputting toner to a contact section where the cleaning member is in contact with the belt member, wherein: after toner is input to the contact section where the cleaning member is in contact with the belt member by the toner input unit, the image adjusting unit forms the test pattern on the belt member, and after toner is input to the contact section where the cleaning member is in contact with the belt member and then the belt member makes one or more revolutions, the image adjusting unit forms the test pattern on the belt member.
