发明名称 Image forming apparatus, landing position shift correction method, and landing position shift correction sheet member
摘要 A disclosed image forming apparatus includes a recording head configured to jet liquid droplets; a pattern forming unit configured to form, on a water-repellent surface of a water-repellent sheet member, an adjustment pattern used for correcting shifts in landing positions of the liquid droplets, wherein the adjustment pattern includes plural liquid droplets that are separated from each other, and the water-repellent surface having a water-repellent property is formed on at least a part of a surface of the water-repellent sheet member; a reading unit including a light emitting unit configured to irradiate light onto the adjustment pattern and a light receiving unit configured to receive specular reflection light from the adjustment pattern; and a landing position correction unit configured to correct, based on a reading result obtained by the reading unit, the shifts in the landing positions of the liquid droplets that are jetted from the recording head.
