摘要： A liquid discharge head includes nozzles, pressure chambers, a common supply channel, a common collection channel, and an air chamber. The nozzles are configured to discharge liquid. The pressure chambers are communicated with the nozzles, respectively. The common supply channel is communicated with the pressure chambers. The common supply channel includes a displaceable first region in a part of a wall of the common supply channel. The common collection channel is communicated with the pressure chambers. The common collection channel includes a displaceable second region in a part of a wall of the common collection channel. The air chamber faces a surface of the first region and a surface of the second region. The surface of the first region is opposite the wall of the common supply channel. The surface of the second region is opposite the wall of the common collection channel.

摘要： An image inspection apparatus for inspecting an output image on a recording medium by scanning the output image as a scanned image includes an inspection reference image generator to generate an inspection reference image using data of an output-target image; an image inspection unit to determine whether the scanned image includes a defect by comparing a difference between the inspection reference image and the scanned image with a given threshold; and a threshold determiner to determine the given threshold. The threshold determiner computes a difference between the inspection reference image and the scanned image. The threshold determiner determines the given threshold based on the difference between the scanned image and the inspection reference image.

摘要： An image forming apparatus is disclosed that includes an image carrier, a driving source, a rotation detection unit, and a control unit that performs fluctuation pattern recognition processing, control pattern construction processing, speed fine-adjustment processing, and remaining pattern recognition processing. The control unit is configured to perform control pattern correction processing for setting a frequency band of a remaining speed fluctuation to be detected by the remaining pattern recognition processing narrower than a frequency band of a speed fluctuation to be detected by the fluctuation pattern recognition processing and correcting the speed control pattern so as to be a pattern capable of reducing even the remaining speed fluctuation based on a remaining speed fluctuation pattern recognized by the remaining pattern recognition processing.
