Abstract (en)

[origin: EP2105803A2] An image forming apparatus is provided. A second photoconductor is disposed at a downstream side of a first photoconductor in a moving direction of a medium. First and second exposure units form first and second electrostatic latent images on the first and second photoconductors line by line at first and second exposure timing intervals in first and second exposure enabling time periods based on successive lines of first and second image data, respectively. A correction unit corrects at least one of the first and second exposure timing intervals. A change unit changes the second exposure enabling time period so as to suppress a difference between the number of the successive lines of the first image data and the number of the successive lines of the second image data.
