An image forming apparatus includes a conversion unit, an image forming unit, a controller, a conveyance unit, a measurement unit, a determination unit, an adjustment unit, and a generation unit. The conversion unit converts image data based on conversion condition. The image forming unit forms and fixes an image to a sheet. The controller controls to create first and second test sheets having respective reference and measurement images. The first and second test sheets are conveyed. The test images are measured. The determination unit determines first and second information regarding positions. The adjustment unit adjusts an image forming condition based the measured test images. The conversion condition is generated based on a second measurement result. A first reference image length in a direction in which the first test sheet is conveyed is longer than a second reference image length in a direction in which the second test sheet is conveyed.
