Abstract
An image forming apparatus includes: a photoconductor; an electric charging device charging the photoconductor; an exposure device exposing a portion of the photoconductor charged by the electric charging device to light based on image information, to form an electrostatic latent image; a first charge eliminating device emitting light to the photoconductor so as to eliminate an electric charge on a surface of the photoconductor; a second charge eliminating device emitting light to the photoconductor so as to eliminate an electric charge on a surface of the photoconductor, a wavelength of the light emitted by the first charge eliminating device being different from a wavelength of the light emitted by the second charge eliminating device; and a controller selectively operating the first and second charge eliminating devices depending on an image content of the electrostatic latent image in an image forming process.
