Abstract:
1. An image forming apparatus, comprising: a photosensitive medium; a charger to charge the photosensitive medium; an exposing unit to expose light to the photosensitive medium to form a latent image on the photosensitive medium; a developing unit which is disposed opposite to the photosensitive medium to develop the latent image into a visible image; a density sensing unit to sense a density of an area of the photosensitive medium; and a controller to determine whether a preset developing condition corresponds to a background image generating condition based on the density sensed by the density sensing unit and to adjust the developing condition based on the determination, the controller controlling the density sensing unit to sense a density of a non-image area on the photosensitive medium in a first test condition in which a background image is less likely to be generated compared with the preset developing condition and to sense a density of the non-image area on the photosensitive medium in a second test condition in which the background image is more likely to be generated compared with the preset developing condition.
