摘要： An image forming apparatus includes a carriage, a drive mechanism, a flexible harness, and a support member. The carriage includes a recording head to jet liquid droplets. The drive mechanism, which moves the carriage in a main scanning direction, includes a belt extending in the main scanning direction. The flexible harness, connecting the recording head and another unit, transmits signals between the recording head and another unit. The support member supports the flexible harness in an upright position over the belt. The flexible harness is routed at least partially in the main scanning direction of the carriage. The support member includes a regulation member at an exit portion of the support member to set a vertical height of the support member at the regulation member smaller than a width of the flexible harness.

摘要： An image forming apparatus includes a carriage carrying a recording head configured to discharge a droplet. A landing position error detecting pattern is formed on a pattern forming member. Based on a result of reading the landing position error detecting pattern, a landing position error of the droplet discharged by the recording head is corrected. Either a first pattern or a second pattern is selected as the landing position error detecting pattern, depending on a surface condition of the pattern forming member. The first pattern produces a relatively small amount of specular reflection compared with diffused reflection, while the second pattern produces a relatively large amount of specular reflection compared with diffused reflection, upon irradiation with light.
