摘要： An image forming apparatus capable of detecting the density of an image patter with a sufficient accuracy irrespective of the color and/or the density of the image pattern, making it possible to carry out color stabilizing control of an output image with high accuracy. An image pattern formed on a transfer material is read by an optical sensor, and based on information on the image pattern, image forming conditions are controlled by a controller. In accordance with the color and the density of the image pattern, an accumulation time of the optical sensor is set.

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 configures a normal transfer potential in a yellow primary transfer unit, and configures a transfer potential which does not cause any retransfer phenomenon of a yellow measurement image in image carriers located on the downstream side of the yellow primary transfer unit. When a color difference obtained from a reference density and a density of a measurement image on an intermediate transfer belt becomes equal to or larger than a prescribed value, the image forming apparatus determines that multinary-color density adjustment is required.
