Patent ID: 7920157

Claim:
An image forming apparatus for forming a toner image on an image bearing member based on image data, the image forming apparatus comprising: a charging unit configured to charge the image bearing member; an exposure unit configured to form an electrostatic latent image on the image bearing member by exposing the image bearing member that has been charged; a development unit configured to develop the electrostatic latent image with toner, wherein the development unit develops the electrostatic latent image into a toner image with density according to electric intensity generated between the development unit and the image bearing member; a determination unit configured to determine whether the toner image formed on the image bearing member is a first image formed of an equal or smaller number of consecutive dots than a predetermined number in a predetermined direction or a second image formed of a larger number of consecutive dots than the predetermined number; and a control unit configured to control an exposure amount to expose the image bearing member by the exposure unit so that the electric intensity for forming the first image is higher than the electric intensity for forming the second image.
