Claim:
An image forming apparatus comprising: an image forming unit developing an electrostatic latent image formed on an image carrier to form a specified toner image; a primary transfer unit transferring the toner image formed by the image forming unit to an intermediate transfer member; and a secondary transfer roller secondarily transferring the toner image transferred to the intermediate transfer member to a recording medium, whereby image adjustment is performed by detecting a toner image constituting an image adjustment pattern, which is formed by the image forming unit and transferred to the intermediate transfer member, wherein on the intermediate transfer member, a leading pattern longer than a circumference of the secondary transfer roller is formed at a leading position in a travelling direction of the intermediate transfer member ahead of the image adjustment pattern by using a toner that is highest in brightness among toners used for the image adjustment pattern or a toner that is higher in brightness than any toner used for the image adjustment pattern.
