    摘要： Provided is an inkjet recording device that has a conveying unit for conveying a recording medium, plural recording head groups each structured by plural unit heads disposed along the conveying direction, and an ink receiving unit for receiving ink discharged from the unit heads. The recording head groups, correspond respectively to plural individual recording regions which are sectioned off in the recording medium transverse direction which is orthogonal to the conveying direction, are disposed so as to be at respectively different positions at adjacent individual recording regions along the conveying direction. The ink receiving unit is disposed so as to face ink drop discharging surfaces of the unit heads. The conveying unit is plural conveying belts disposed at positions evading trajectories of the ink drops from the unit heads as seen in a direction of a line normal to the recording medium so as to be divided in the conveying direction.

    摘要： A registration pattern is formed on an intermediate transfer belt by using one photosensitive body. Pattern parts transferred onto the intermediate transfer belt vary in spacing due to speed variation occurring at the transfer time. The passing timing of the registration pattern is read through a read section placed downstream from the photosensitive body and speed (position) variation is sensed. The sense data is gotten over several cycles of the intermediate transfer belt and a low-frequency component caused by thickness unevenness of the intermediate transfer belt is extracted. The extracted data is subjected to the effects of variations at both the formation time and read time of the registration pattern and thus is corrected of calculating true speed (position) variation data. For example, a drive roll is controlled based on the data and an image is formed.
