Abstract
In an inkjet printer where any two ink ejection parts provided upstream and downstream in a conveyance direction of a base member are referred to as first and second ink ejection parts, the first ink ejection part ejects a first ink, a droplet of which when deposited on the base member has a surface tension decreasing with time. The second ink ejection part ejects a second ink, a droplet of which when deposited on the base member has a surface tension that is substantially equal to a surface tension of the droplet of the first ink deposited on a position adjacent to the droplet of the second ink. The printer can therefore make substantially equal the surface tensions of droplets of the first and second inks, deposited on adjacent positions, thus reducing bleeding in a boundary between areas of the inks or variation in the position of the boundary.
