An image formation apparatus is disclosed, in which two or more toner images in different colors are superposed on an endless conveyance belt to form a color image for imprinting, and the color image for imprinting is imprinted to an imprinting medium. The image formation apparatus includes: an image formation unit for forming plural sets of marks for position error compensation for compensating for a position error of the different colors, which position error is generated when forming the color image on the conveyance belt; a detection unit for detecting position information about positions of the sets of marks for position error compensation formed on the conveyance belt by the image formation unit; and a control unit for performing a position error compensation process based on the position information detected by the detection unit. The control unit determines the number of detected positions of the marks for position error compensation from the position information for each of the sets, and performs the position error compensation process based on the position information of the marks for position error compensation of a set, the number of detected positions of which set is equal to a predetermined number out of all the sets of the marks for position error compensation.
