    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.

    摘要： An image-forming device which is equipped with an image-holding member, an exposure section provided with plural light-emitting portions arranged in a first direction, a movement section that relatively moves the exposure section and the image-holding member in a second direction that intersects with the first direction, and a light-emission control section. The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formed on the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.
