Abstract
An image forming apparatus includes a control unit and first and second image scanning devices. The first and second image scanning devices scan the same surface of the same sheet with an image formed thereon on a sheet-conveying pathway. The image forming apparatus adjusts an image forming condition based on information acquired through the scan by the first and second image scanning devices. The first image scanning device scans only a part of an area in the main scanning direction. The second image scanning device scans an area across the image forming width in the main scanning direction. The control unit detects an anomalous value based on the information acquired through the scan by the second image scanning device, and prompts cleaning of the first and second image scanning devices in response to detection of the anomalous value.
