An image forming apparatus includes a feeding unit configured to feed a sheet, an image forming unit configured to form a measurement image on the sheet fed by the feeding unit, a measuring unit configured to measure the measurement image formed on the sheet by the image forming unit, and an adjustment unit configured to perform an adjustment operation on basis of a measurement result of the measurement image. In this case, the image forming unit forms the measurement image of a first side of the sheet and forms a setting aid image on a second side that is different from the first side, and the setting aid image shows information describing the direction of the sheet for setting in the feeding unit and information for prompting to set the sheet with the second side up in the feeding unit.
