摘要： An image forming apparatus that is capable of reducing a sequential variation of graininess and keeping imaging quality. An exposure unit exposes the photoconductor to a light beam to form an electrostatic latent image. A development unit develops the electrostatic latent image with a toner. A change unit changes a height of toner image by changing an exposure spot area of the light beam on the photoconductor. A formation unit forms test patterns corresponding to different exposure spot areas on a recording sheet. A read unit reads the test patterns. A control unit detects graininess of each test pattern based on information about the test patterns read by the read unit, determines an exposure spot area where the graininess becomes good relatively, and controls the height of toner image on the photoconductor by setting the exposure spot area determined so as to be an exposure spot area for image formation.

摘要： A reader unit A reads a pattern image formed on a first printing medium to obtain a first luminance value. A color processing unit converts into a density value using first conversion information. CPU creates an image processing condition LUTa based on the density value. A photo sensor reads a pattern image formed on an image carrier. CPU corrects LUTa based on a density value of the pattern image read by photo sensor. A printer unit forms a pattern image on a second printing medium different using the corrected LUTa. CPU determines second conversion information for the second printing medium based on a second luminance value from the pattern image on the second printing medium, the first luminance value and the first conversion information.

摘要： An image forming apparatus includes an image forming unit, a decision unit, an output unit, a control unit, and a setting unit. The image forming unit forms an image on an image bearing member. The decision unit decides a first image forming condition of the image forming unit for forming the image at a width that is wider than a predetermined width. The output unit outputs a signal in accordance with the thickness of the image. The control unit causes the image forming unit to form a measurement image having a width that is narrower than or equal to the predetermined width. The setting unit sets a second image forming condition of the image forming unit so that the thickness of the image that is narrower than or equal to the predetermined width becomes thinner than or equal to the predetermined thickness.
