摘要： An apparatus includes an image-processing-unit that generates tag information indicating whether each of pixels of a first-resolution image data is a pixel of a character or a line, a resolution-converting-unit that converts the first-resolution image data to image data with a second resolution higher than the first resolution, and a light-source-driving-unit that drives light-source according to the second-resolution image data. The resolution-converting-unit includes an image-matrix-acquiring-unit that acquires an image matrix being image data and tag information with the first resolution in an area containing a target-pixel and pixels around the target-pixel, a pattern-matching-unit that determines whether the target-pixel is a pixel of an edge of a character or a line based on the image matrix, and a first-converting-unit that, when the pixel is the edge pixel, converts the image data to image data with the second resolution of a pattern determined in accordance with a layout of the target-pixel.

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： In an image forming apparatus and an image density control method that are capable of suppressing the amount of toner consumed for a purpose other than image formation and responding to variation in the development ability of a development device due to environmental variation and the like such that a constant image density is obtained, the image density is maintained at a substantially fixed level by first target output value correcting means in accordance with a toner replacement amount and without consuming toner, and adjustment of the image density accompanying variation in the development ability due to environmental variation and the like is dealt with by second target output value correcting means in accordance with a toner pattern detection result. Hence, the frequency with which the toner pattern is detected in order to maintain the image density at a fixed level can be reduced in comparison with a case in which the image density is maintained at a fixed level on the basis of the toner pattern detection result alone, and as a result, the toner consumption amount can be suppressed.
