An image forming apparatus includes an intermediate transfer belt and a developer unit. The image forming apparatus includes a cooling unit, a cleaning roller, and an auxiliary brush. The cooling unit cools a predetermined component by sending air by a fan inside the image forming apparatus. The cleaning roller removes remaining toner on the intermediate transfer belt at an upstream side of a region facing the developer unit in a rotationally moving direction of the intermediate transfer belt and at an upstream side of a region with which the image carrier is in contact in the intermediate transfer belt. The auxiliary brush located on an outer surface of the developer unit so as to close the clearance between the intermediate transfer belt and the developer unit and is in contact with the intermediate transfer belt to clean the intermediate transfer belt.

Disclosed is an image forming apparatus, including: a job receiver that receives a print job; a printer that executes an image forming in accordance with the print job received by the job receiver; and a hardware processor that: receives an adjustment content and a setting of an execution starting condition of an adjustment for an adjustment item relating to the image forming, and registers the adjustment content and the execution starting condition as a profile; and executes the adjustment in accordance with the adjustment content set in the registered profile when the execution starting condition set in the profile is satisfied.

An image forming apparatus includes image bearing members, an intermediate transfer member, a transfer unit, a control unit, and image forming units respectively corresponding to the image bearing members and each configured to form and transfer an image to the intermediate transfer member, which is then transferred to the conveyed recording material. Image patterns on the intermediate transfer member are detected for positional deviation detection. In a first mode, timing of image formation is determined using a first reference. In a second mode, timing of image formation is determined using a second reference. Based on timings at which formed image patterns are detected, the control unit, in the second mode, corrects timing of image formation performed by a second image forming unit or corrects timing at which the recording material is conveyed to the transfer unit.

An intermediate transfer belt includes a base layer that has ionic conductivity and is a thickest layer out of multiple layers making up the intermediate transfer belt with respect to the thickness direction of the intermediate transfer belt, and an inner layer having electronic conductivity and a lower electrical resistance than the base layer.

An image forming apparatus is enabled to perform a first operation that forms an image with a first developer of one color transported by a first transport unit and held by a first developer holder that is rotating and a second operation that forms an image with a second developer of another color transported by a second transport unit and held by a second developer holder that is rotating. In the first operation, a rotational speed of the first developer holder and a rotational speed of the second developer holder are a first rotational speed and a transport speed of the first developer transported by the first transport unit and a transport speed of the second developer transported by the second transport unit are a first transport speed, and in the second operation, the rotational speed of the first developer holder and the rotational speed of the second developer holder are a second rotational speed lower than the first rotational speed, the transport speed of the first developer transported by the first transport unit is a second transport speed lower than the first transport speed and the transport speed of the second developer transported by the second transport unit is higher than the second transport speed.
