An image formation apparatus that comprises: a plurality of laser diodes that form color-component images that correspond to a plurality of color components onto a plurality of corresponding photosensitive drums respectively; and a transfer belt onto which the color-component images that are formed on the respective photosensitive drums are transferred; and adjusts the image formation timing based on the positions of the color-component images that are transferred to the transfer belt; and when adjusting the image formation timing, the respective laser diodes form color-component images at formation intervals that correspond to an integral multiple of the period of a periodic noise. Adjustment of the image formation timing is performed at high precision.
