More Information
Summary:An image forming apparatus including an image forming unit, a fixing unit, a reading unit, a reference member, and a controller is described. The image forming unit forms an image and a detection image on a sheet. The detection image is used for detecting geometric characteristics of an image to be formed on a sheet by the image forming unit. The fixing unit fixes the image and the detection image formed by the image forming unit on the sheet. The reading unit reads the detection image on the sheet. The controller adjusts geometric characteristics of the image to be formed on a sheet based on a reading result of the detection image by the reading unit, and controls the reading unit to read the reference member and executes shading correction based on a reading result of the reference member.
