Abstract
An image forming apparatus includes a first image forming unit that forms toner images based on image data on first image carriers; a second image carrier, on which the toner images formed on the first image carriers are transferred; a second image forming unit that transfers the toner images transferred on the second image carrier onto a transfer medium; a test pattern generating unit that generates a test pattern group with a predetermine length in a moving direction of the second image carrier; and an adjusting unit that determines a method to adjust an image formation condition for the first image forming unit using the test pattern group, based on a relationship between the predetermined length and a length of an image area, in which a print image based on the image data is formed, in a sub-scanning direction corresponding to the moving direction of the second image carrier.
