Abstract
An image forming apparatus includes: at least one first image carrier configured to carry an electrostatic latent image thereon; an image writing unit; a second image carrier configured to move along a transfer position facing to the at least one first image carrier; a first transfer unit provided opposite to the at least one first image carrier; a second transfer unit configured to transfer the subject image to a transfer material; a test pattern detection unit configured to detect the test pattern image; a control unit configured to correct an image forming condition of the subject image based on a result from the detection of the test pattern image, wherein the test pattern image is provided on the second image carrier at an area being out of the image forming area and being at the same range as the subject image in a scanning direction.
