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.

摘要： A side wall surface of a carriage is disclosed with two first projection parts and a second projection part that define the inclination of a reflective optical sensor in its vertical direction. The two first projection parts are arranged at the same height position with a detection surface as a reference, and the second projection part is arranged at a position higher than the first projection parts with the detection surface as the reference. The second projection part has a first part higher in position from the side wall surface of the carriage than the first projection parts and has a second part lower in position than the first part. The second part has a screw hole into which a clamping member for fixing the reflective optical sensor to the second part is tightened.
