An image formation apparatus includes: a developer image formation section configured to form plural developer images whose colors are different from each other; a transfer device configured to transfer the plural developer images onto a medium while superimposing the developer images on each other, thereby to form a multi-color developer image on the medium; and a memory configured to store information on priority color settings including plural priority colors and transfer orders of the plural developer images which are predetermined for the respective priority colors. When one of the priority colors is selected, the image formation apparatus transfers the plural developer images sequentially in the transfer order for the priority color setting of the selected priority color.
