Abstract
An image forming apparatus includes an image forming unit that forms an image on a sheet based on first image data, an image reader that reads a surface of the sheet having the image formed thereon and generates second image data, and a controller that performs detection to detect a defect of the formed image depending on a difference between the first image data and the second image data. The controller analyzes a setting for the sheet or the second image data to determine a sheet color of the sheet and restricts the detection depending on the sheet color.
