Abstract: An image formation apparatus includes a first discharge unit to form an image on a recording medium; and a second discharge unit including a nozzle line that discharges transparent droplets on the image formed on the recording medium. The second discharge unit moves in a first direction relative to the recording medium and the nozzle line has nozzles in a second direction orthogonal to the first direction. After the image formation, the second discharge unit discharges the transparent droplets from the nozzles spaced at m?1 nozzle intervals to form a row of dots in the second direction, and repeats the forming while moving to form m rows in the first direction, such that the dots in the rows are formed at m?1 nozzle intervals and positions of the dots between n-th and n?1-th rows are displaced together by one nozzle in the second direction.
