摘要： An image forming apparatus includes an image carrier, a rotation-position detector, a development device, a transfer unit, a density sensor, and an image-forming-condition determination unit. The density sensor senses a density of a toner image on a transfer body. The image-forming-condition determination unit forms an image pattern, acquires periodical density variation information sensed by the density sensor and detection information of the rotation-position detector, and determines an image forming condition based on the periodical density variation information and the detection information acquired. The image carrier and the transfer body are different in linear velocity in an image formation in which the toner image is transferred to a recording medium. The image carrier and the transfer body are controlled to be equal in linear velocity in an information acquisition in which the image-forming-condition determination unit acquires the periodical density variation information and the detection information.

摘要： Latent image graduations formed on an intermediate transfer belt are read by a first sensor portion. Latent image graduations formed on a photoconductive drum are read by a second sensor portion. When an image is transferred from the photoconductive drum to the intermediate transfer belt on the basis of the information read by these sensor portions, the position of the image on the photoconductive drum is controlled to match the position of the image on the intermediate transfer belt. The first sensor portion and the second sensor portion are held integrally by the holding member. Accordingly, variations due to a temperature change of relative positions between the sensor portions or difference in vibrations of the respective sensor portions which may cause errors when aligning the images are reduced.

摘要： An image forming apparatus includes an adjustment sequence controller that causes first to third adjustment processes to be executed. In the first adjustment process, if a second registration mark having reduced calculation errors of shifts of toner-image formation positions as compared with those of a first registration mark is formed in a normal way, the toner-image formation positions are adjusted by using the second registration mark. In the second adjustment process, if the second registration mark is not formed in the normal way, the toner-image formation positions are adjusted by using the first registration mark. In the third adjustment process, if the second registration mark is formed in the normal way after the second adjustment process, the toner-image formation positions are adjusted by using the second registration mark.
