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 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 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.
