Abstract
An image forming apparatus includes image forming sections for respective colors, the image forming sections facing an outer surface of an intermediate transfer belt on an outward path. A transfer roller is provided on a returning path and is movable to a contact position where the transfer roller is pressed against the intermediate transfer belt or to a detachment position where the transfer roller is detached from the intermediate transfer belt. A density sensor is provided for detecting a density of toner image on the intermediate transfer belt. In an image quality adjustment operation, image forming sections form a toner image row on the intermediate transfer belt, and the density sensor measures densities. A length of the toner image row is smaller than a length of the intermediate transfer belt between the endmost photoreceptor drum on the downstream side and the transfer roller.
