摘要： An image forming apparatus includes: a charging unit that uniformly charges a surface of a latent image carrier; a latent-image forming unit; a developing unit that performs development by causing toner to electrostatically adhere on the surface of the carrier; a transfer unit that transfers a toner image onto a recording medium; and an image-density adjusting unit that causes to form a multi-gradation patch pattern on the surface of the carrier, that causes to detect potentials of latent image patches in the multi-gradation patch pattern, that causes to detect a toner adhesion amount on each toner patch, and that performs control of an image density. One of part and all of the low-density latent image patches is a dot-dispersed latent image patch in which the arrangement of unit dot latent images in the basic dot matrix is determined so that a minimum center-to-center distance having a smallest value is maximized.

摘要： An image forming apparatus includes an image processor, a converter, a light source driver, an identifying unit, and a pattern generator. The image processor generates image data of first resolution and generates tag information indicating whether to perform image processing and associated with pixels of the image data of first resolution. The converter converts the image data of first resolution to image data of a higher second resolution. The light source driver drives a light source using a modulation signal corresponding to the image data of second resolution. The identifying unit identifies a target pixel to be subjected to image processing in the image data of first resolution based on the tag information. The pattern generator generates an image-processed pixel pattern of the second resolution according to the target pixel. The converter converts the target pixel in the image data of first resolution to the generated image-processed pixel pattern.

摘要： An adjustment time reduction mode of reducing adjustment operation time is provided such that a user can set the adjustment time reduction mode in which a user arbitrarily reduces the adjustment operation time, depending on the user's situation. An apparatus performing adjustment operation at a predetermined timing, monitors a timing at which the adjustment operation is to be performed and visually notifies a user of the timing at which the adjustment operation is to be performed before execution of a job requested by the user. When the adjustment time reduction mode is set, the apparatus reduces a time for the adjustment operation during execution of the job requested by the user, and the apparatus is caused to operate in the adjustment time reduction mode until the job is completed.

摘要： An image forming apparatus includes a detector, a calculator, and a corrector. The detector receives brightness values obtained from an image printed based on image data. The image includes a plurality of streaks and non-streak portions having image density differences with the plurality of streaks. The detector detects a first streak width, a first brightness difference between a brightness value of the first streak and a brightness value of a non-streak portions, a second streak width wider than the first streak width, and a second brightness difference between a brightness value of the second streak and a brightness value of a non-streak portion. The calculator calculates a correction coefficient corresponding to the first streak width based on the first brightness difference and the second brightness difference. The corrector corrects an image density corresponding to the first streak width in the image data based on the calculated correction coefficient.

摘要： An image forming apparatus which enables the user to easily remove a sheet bundle left in the apparatus after a bookbinding-mode job is stopped in the middle of execution thereof. In a bookbinding mode of the apparatus, in a sheet stacking section, a plurality of sheets having images formed thereon are stacked as a sheet bundle; in a gluing section, glue is applied to an end face of the sheet bundle; and in a bonding section, a cover sheet is bonded to the sheet bundle to wrap the sheet bundle in the cover sheet. When a bookbinding-mode job is canceled during execution thereof, in the gluing section, glue is applied to the sheet bundle stacked in the stacking section before the job is stopped, and a discharge section discharges the glue-applied sheet bundle which is neither wrapped nor trimmed.
