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： An image forming apparatus has a calibration mode in which a calibration image is formed on a print medium to correct image forming conditions. The image forming apparatus detects print medium information to determine, on the basis of the print medium information, whether the print medium is a sheet recommended as a print medium for use in the calibration mode. The image forming apparatus sets calibration conditions corresponding to the determined recommended sheet. The image forming apparatus corrects the image forming conditions on the basis of the set calibration conditions.

摘要： An image color correction method and an image forming apparatus are provided, which are capable of correcting an image color with much higher accuracy. A first light (red light) is irradiated on patch image (for example, an image of cyan color) formed on a sheet by the image forming apparatus, and a second light (red light) is irradiated on the vicinity of the patch image on the sheet, respectively by the image forming apparatus. The light amount of the second light is adjusted so that the brightness of the second light coincides with the brightness of the patch image irradiated by the first light. Based on the light amount adjusted for correcting the color of the image outputted by the image forming apparatus, the image forming condition of the image forming apparatus is set.
