Patent ID: 7539429

Claim:
An image forming apparatus, comprising: an image carrier; a charging section which is provided with a charge voltage and charges surface of said image carrier; an exposing section for forming an electrostatic latent image on the surface of said image carrier; a developing section which is provided with a development voltage and makes developer adhere to said electrostatic latent image formed on said image carrier so as to form a visible image; a transferring section to transfer said visible image onto a transfer member; a density detecting section to detect a density of said visible image on said transfer member; a development voltage setting section to set a development voltage to be provided to said developing section based on said density detected by said density detecting section; a charge voltage setting section to set a difference between said charge voltage provided to said charging section and said development voltage set by said development voltage setting section into a value in a predetermined range; and an exposure quantity setting section to set an appointed exposure quantity with respect to said charge voltage.
