Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: an image forming unit that forms an image on an object; a control unit to control the image forming unit to: form a first pattern on the object; and form a second pattern on the object at timing different from that of the first pattern, wherein the first pattern includes a first line segment and a second line segment, the second line segment being separated from the first line segment on an extended line of the…
