Abstract: In an image forming apparatus, an image forming unit forms a first image of a first color and a second image of a second color. An obtaining unit obtains information related to relative positions of a first measurement image, which is formed on an image carrier, of the first color and a second measurement image, which is formed on an image carrier, of the second color. A generation unit generates correlation data based on first information corresponding to a first image forming speed and second information corresponding to a second image forming speed. A controller, in a case where the image forming unit forms an image at the second image forming speed, corrects relative positions of the first image and the second image based on the first information in advance and the correlation data.

Abstract: An image forming apparatus includes a determiner for determining whether to execute a first image formation in an acquisition mode, in which an image forming operation is carried out using an acquired timing, or a second image formation in a non-acquisition mode, in which the image forming operation is carried out using exposure timing acquired in a previous acquisition mode. The determiner makes the determination on the basis of a current output of a temperature sensor and a previous output of the temperature sensor. When the determiner determines the execution of the first image formation, driving speeds of a first driver and a second driver are set, before the execution of the operation in the acquisition mode, on the basis of the current output of the temperature sensor, and the operation in the acquisition mode and the image formation are carried out using the driving speeds currently set.
