    摘要： An image forming apparatus includes a recording head in which a plurality of nozzles for discharging liquid droplets; and a pattern forming unit configured to form a test pattern used for positional deviation adjustment including a first pattern serving as a reference pattern and a second pattern serving as an adjustment pattern. The first pattern and the second pattern each are a linear pattern that is parallel to a nozzle arrangement direction and has a disconnected portion. The disconnected portion of the first pattern and the disconnected portion of the second pattern are shifted from each other in the nozzle arrangement direction.
