ABSTRACT:
The image forming apparatus has: a head which has a liquid ejection surface and performs liquid ejection in which liquid is ejected from the liquid ejection surface; an intermediate transfer body moving in a movement direction with respect to the head and having an image forming surface opposing the liquid ejection surface of the head and a rear surface which is reverse to the image forming surface and on which a line pattern constituted by pattern elements is formed, the image forming surface having an image forming region in which an image is formed by the liquid ejected from the liquid ejection surface of the head, the pattern elements being arranged equidistantly in the movement direction; a transfer device which transfers the image formed in the image forming region of the intermediate transfer body to a recording medium; a reading device which is provided on an upstream side of the head in terms of the movement direction of the intermediate transfer body and reads light reflected by the line pattern; and an ejection control device which determines a movement speed and a movement distance of the intermediate transfer body from result obtained by reading the light by means of the reading device, generates an ejection control signal for the head according to the determined movement speed and the determined movement distance of the intermediate transfer body, and controls the liquid ejection of the head according to the ejection control signal.
