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 disclosed image forming apparatus includes a carriage having a head for jetting droplets; a pattern forming unit configured to form, on a belt, a pattern used for detecting displacement of landing positions of the droplets; a reading unit configured to scan the belt before the pattern formation to output a first result, and scan the pattern to output a second result; a correcting unit configured to correct the displacement based on the second result; a frequency analyzing unit configured to calculate frequencies of the belt and amplitudes of respective frequency components based on the first result; and a peak frequency calculating unit configured to calculate peak frequencies of the belt based on the frequencies of the belt and the amplitudes of the frequency components, the peak frequencies being frequency components whose amplitude exceeds a predetermined level. The pattern is formed at a frequency different from the peak frequencies.
